=="Once per turn"==
These kinds of effects can be seen by the fact that the effect starts with "once per turn" and possibly another [[Activation Requirement]] as well.

"Once per turn" effects can be identified by the text "once per turn" in their [[activation requirement|activation conditions]].
 +
 
 +
These kinds of effects can only be used once per turn per card, while that card is face-up in its current location. (Even if that effect's activation is [[negate]]d, it cannot be activated again that turn.) This restriction only applies to that copy of the card; if a player is in [[possession]] of multiple cards with the same name that have the same "Once per turn" effect, they can activate each one during that turn. Additionally, if a card that activated its "Once per turn" effect changes locations or is flipped face-down, its effect can be activated again during that same turn.
  
 
Example:
 
Example:
* '''Once per turn:''' You can [[detach]] 1 [[Xyz Material]] from this card, then [[target]] 1 [[Defense Position]] monster on the [[field]]; change it to [[face-up]] [[Attack Position]], and if you do, it loses 600 [[ATK]].
+
* '''Once per turn''': You can [[detach]] 1 [[Xyz Material]] from this card, then [[target]] 1 [[Defense Position]] monster on the [[field]]; change it to [[face-up]] [[Attack Position]], and if you do, it loses 600 [[ATK]].
 
 
Typically, these kinds of effects are either [[Ignition Effects]] or [[Quick Effects]], but they can also be [[Trigger Effects]]. These kinds of effects can only be used once per turn as long as that specific card stays face-up on the field. For example, if "[[Photon Papilloperative]]" [[activate]]s its effect, and then is later [[destroy]]ed that turn, and "[[Xyz Reborn]]" is used to [[Special Summon]] it back from the [[Graveyard]], then you can once again use the effect as it has left the field, which "resets" the once per turn condition, thereby allowing it to activate once again. This principle also applies for Spell and Trap Cards. If you control multiple of the same card, you can activate both of their effects as well.

+
For example, if "[[Barrel Dragon]]" [[activate]]s its effect, it cannot activate its effect again that turn while it remains face-up on the field. However, if after activating its effect it is [[destroy]]ed and sent to the [[Graveyard]], then [[Special Summon]]ed from the Graveyard by "[[Call of the Haunted]]", it can then activate its effect again during that turn. Similarly, if a player controls two copies of "Barrel Dragon", they can activate the effects of both during the same turn.

"Only once per turn" effects can be identified by one of the following [[condition]]s: "You can only activate 1 "X" per turn" or "You can only activate/use [reference to effect] of "X" once per turn" (Japanese: このカード名の (''Effect #'') 効果は1ターン(デュエル)に1度しか使用(発動)できない。). Cards stating "once per Duel" instead of "once per turn" work in the same way, but apply for the entire Duel instead.
  
==Only once per turn effects==
+
The reference to the effect is most often "the effect" or "this effect", but can also be other references such as "1 of these effects", "each of the preceding effects" etc. depending on the structure of the card's text.
These kinds of effects can be seen by the fact effect has either "You can only activate 1 "X" per turn" or "You can only activate/use the/this effect of "X" once per turn." Cards stating "once per Duel" instead work in the same way (they just apply for the entire Duel instead).
 
  
Like with "once per turn effects", these can be Ignition Effects, Quick Effects or Trigger Effects; however, unlike them, these effects can only be used once per turn, regardless of them being reset, or you having multiple copies.
+
If an effect has this condition, each player can only activate that effect of cards with the same name once per turn. This kind of condition is not affected by cards' names being changed; for example, if "[[Fairy Archer]]" activates its effect, even its name is changed by "[[Hero Mask]]" later that turn, it cannot activate its effect again that turn.<ref>{{cite book  |author=Konami  |title=Yu-Gi-Oh!

Japanese: このカード名の (''Effect #'') 効果は1ターン(デュエル)に1度しか使用(発動)できない。(Kono kādo na no (''Effect #'') kōka waāō)
+
If a card states "You can only '''use''' this effect of (''card name'') once per turn", then even if the activation is negated, you cannot activate it once again. On the other hand, if a card states "You can only '''activate''' this effect of (''card name'') once per turn", that effect can be activated again that turn if its activation is negated.
  
 
Example 1 ([[Spellbook of Secrets]]): [[Add]] 1 "[[Spellbook]]" card from your [[Deck]] to your [[hand]], except "[[Spellbook of Secrets]]". '''You can only activate 1 "Spellbook of Secrets" per turn.'''
 
Example 1 ([[Spellbook of Secrets]]): [[Add]] 1 "[[Spellbook]]" card from your [[Deck]] to your [[hand]], except "[[Spellbook of Secrets]]". '''You can only activate 1 "Spellbook of Secrets" per turn.'''
  
This means you cannot activate multiple copies of "Spellbook of Secrets", since it states you can only activate one of them per turn. However, if the activation of a cards with such statements is negated, you can activate it once again.
+
If a player activates "Spellbook of Secrets" and its activation is not negated, this means that player cannot activate the card "Spellbook of Secrets" again during that turn.
  
 
Example 2 ([[Bacon Saver]]): During either player's [[Battle Step]], while an [[attack]] is occurring: You can [[banish]] this card from your Graveyard; [[negate]] the attack. '''You can only use the effect of "[[Bacon Saver]]" once per [[Duel]].'''
 
Example 2 ([[Bacon Saver]]): During either player's [[Battle Step]], while an [[attack]] is occurring: You can [[banish]] this card from your Graveyard; [[negate]] the attack. '''You can only use the effect of "[[Bacon Saver]]" once per [[Duel]].'''
  
If a card states "You can only '''use''' this effect of (''card name'') once per turn", then even if the activation is negated, you cannot activate it once again.
+
If a player activates the effect "Bacon Saver", this means that player cannot activate the effect of "Bacon Saver" again during that same Duel, even if the activation of the effect was negated.

These effects can be identified by the text "(You can only gain this effect once per turn.)".
 
 
==You can only gain this effect once per turn==
 
Unlike the other "Once per turn" effects, these work a bit differently. These can be identified by the text "(You can only gain this effect once per turn.)". Most such effects allow the player to perform an additional [[Normal Summon]]/[[Normal Set|Set]] that turn without starting a [[Chain]], but only one of these effects can be gained per turn. Even if the player controls both "[[Evilswarm Castor]]" and "[[Fire Formation - Tensu]]", the player still can only gain the effect of one to perform an extra Normal Summon.
 
 
 
Example:
 
* "During the turn this card was Normal Summoned, you can Normal Summon 1 "[[lswarm]]" monster in addition to your Normal Summon/[[Normal Set|Set]]. '''(You can only gain this effect once per turn.)'''"
 
 
 
Cards and effects that start a [[Chain]], then perform the Normal Summon immediately after [[Resolve|resolving]] (such as "[[Pahunder]]" and "[[Ultimate Offering]]") as well as cards and effects that change the maximum number of Normal Summon/Sets that turn (such as "[[Double Summon]]" and "[[Chain Summoning]]") can still be used, regardless of if an effect that specifies "(You can only gain this effect once per turn.)" was used that turn.

Each player can only apply one effect with this text per turn, even if the cards have different names. For example, even if the player controls both "[[Evilswarm Castor]]" and "[[Fire Formation - Tensu]]", the player can only gain the effect of one to perform an extra Normal Summon.

Most effects with this text allow the player to perform an additional [[Normal Summon]]/[[Normal Set|Set]] that turn without starting a [[Chain]], but only one of these effects can be gained per turn. The only cards with this text that do not have such an effect are "[[Zefraath]]" (which grants an additional [[Pendulum Summon]]) and "[[Dice Re-Roll]]" (which allows a player to redo a dice roll).

once per turn

"Once per turn effects" are a kind of card effect. There are three kinds of "Once per turn effects".

The first is typically referred to as a "Once per turn effect". The second is typically referred to as a "Only once per turn effect". The third is typically referred to as an "Additional Normal Summon once per turn effect".

"Once per turn"

BarrelDragon-DPBC-EN-R-1E.png

"Once per turn" effects can be identified by the text "once per turn" in their activation conditions.

These kinds of effects can only be used once per turn per card, while that card is face-up in its current location. (Even if that effect's activation is negated, it cannot be activated again that turn.) This restriction only applies to that copy of the card; if a player is in possession of multiple cards with the same name that have the same "Once per turn" effect, they can activate each one during that turn. Additionally, if a card that activated its "Once per turn" effect changes locations or is flipped face-down, its effect can be activated again during that same turn.

Example:

For example, if "Barrel Dragon" activates its effect, it cannot activate its effect again that turn while it remains face-up on the field. However, if after activating its effect it is destroyed and sent to the Graveyard, then Special Summoned from the Graveyard by "Call of the Haunted", it can then activate its effect again during that turn. Similarly, if a player controls two copies of "Barrel Dragon", they can activate the effects of both during the same turn.

"Only once per turn"

SpellbookofSecrets-REDU-EN-UR-UE.png

"Only once per turn" effects can be identified by one of the following conditions: "You can only activate 1 "X" per turn" or "You can only activate/use [reference to effect] of "X" once per turn" (Japanese: このカード名の (Effect #) 効果は1ターン(デュエル)に1度しか使用(発動)できない。). Cards stating "once per Duel" instead of "once per turn" work in the same way, but apply for the entire Duel instead.

The reference to the effect is most often "the effect" or "this effect", but can also be other references such as "1 of these effects", "each of the preceding effects" etc. depending on the structure of the card's text.

If an effect has this condition, each player can only activate that effect of cards with the same name once per turn. This kind of condition is not affected by cards' names being changed; for example, if "Fairy Archer" activates its effect, even its name is changed by "Hero Mask" later that turn, it cannot activate its effect again that turn.[1]

If a card states "You can only use this effect of (card name) once per turn", then even if the activation is negated, you cannot activate it once again. On the other hand, if a card states "You can only activate this effect of (card name) once per turn", that effect can be activated again that turn if its activation is negated.

Example 1 (Spellbook of Secrets): Add 1 "Spellbook" card from your Deck to your hand, except "Spellbook of Secrets". You can only activate 1 "Spellbook of Secrets" per turn.

If a player activates "Spellbook of Secrets" and its activation is not negated, this means that player cannot activate the card "Spellbook of Secrets" again during that turn.

Example 2 (Bacon Saver): During either player's Battle Step, while an attack is occurring: You can banish this card from your Graveyard; negate the attack. You can only use the effect of "Bacon Saver" once per Duel.

If a player activates the effect "Bacon Saver", this means that player cannot activate the effect of "Bacon Saver" again during that same Duel, even if the activation of the effect was negated.

"You can only gain this effect once per turn"

ConstellarPollux-HA07-EN-SR-1E.png

These effects can be identified by the text "(You can only gain this effect once per turn.)".

Each player can only apply one effect with this text per turn, even if the cards have different names. For example, even if the player controls both "Evilswarm Castor" and "Fire Formation - Tensu", the player can only gain the effect of one to perform an extra Normal Summon.

Most effects with this text allow the player to perform an additional Normal Summon/Set that turn without starting a Chain, but only one of these effects can be gained per turn. The only cards with this text that do not have such an effect are "Zefraath" (which grants an additional Pendulum Summon) and "Dice Re-Roll" (which allows a player to redo a dice roll).
