Ignition Effect

"Ignition" redirects here. For the card named "Ignition" in Japanese, see "Backfire" (manga).

"Buten", an example card with an Ignition Effect.

Ignition Effects (Japanese: 起動効果 Kidō Kōka, "Startup effect") are Spell Speed 1 effects that require a manual activation by the card's controller during their own Main Phase 1 or 2. This type of effect used to be called a Cost Effect in the early days of Yu-Gi-Oh!, which was slightly confusing because not all of those monsters had a cost.

Examples of monsters with Ignition Effects: "Cyber Gymnast", "XYZ-Dragon Cannon", "Bazoo the Soul-Eater", "Blackwing - Gale the Whirlwind", "3-Hump Lacooda", "Card Trooper", "Dark Simorgh", "Lonefire Blossom", "XX-Saber Faultroll" and most Xyz Monsters.

Post-Problem-Solving Card Text, these type of effects will generally be indicated by "Once per turn:", "You can" or "During your Main Phase:", followed by the cost which will end with a semi-colon(;), and lastly, the actual effect which you activated.

Priority

Under previous rules, it was possible to activate an Ignition Effect in response to the monster's own Summon. This was removed from the OCG on March 19, 2011, and from the TCG on April 25, 2012. Ignition Effects can now only be activated during an open game state.

When the turn player Summoned a monster with an Ignition Effect, because they had priority to activate an effect, they could activate the Summoned monster's Ignition Effect before the opponent could activate a fast effect.

For example, the turn player could Summon "Lonefire Blossom" and activate its effect before their opponent could activate "Eatgaboon".
