Changes

| rowspan="4" | [[Cannon Soldier]] and its ilk are classic burn FTK enablers with no once-per-turn restriction which can be used in many strategies. The original was infamous, but spared being Forbidden for so long (unlike its faster Spell counterpart, [[Mass Driver]]) since it has the disadvantage of requiring a Normal Summon or another card to Special Summon it. The game is much faster now, and methods to Special Summon it and its counterparts easily are widespread. In particular, various Link-era burn strategies featuring [[Firewall Dragon]] (now Forbidden) and the player's choice of engine brought them to the fore enough for them to be Forbidden. Amazoness Archer and Toon Cannon Soldier All except MK-2 are technically greater threats than the other two, due to them being also searchable. These cards are Unlimited in the TCG.

| Banishes a Level 7 or higher Dragon from the Deck when sent to the Graveyard, and recovers that monster when banished. No once-per-turn restriction on either effect. Banished Easily Summoned by [[Guardragon Elpy]], and the banished monster (and Wyvern itself) can be recovered with [[Guardragon Pisty]]. Key to [[Guardragon]] -abusing Decks. This card is Unlimited in the OCG.

| High-Level monster with an effect similar to Phantom of Chaos (now Unlimited; see below). Was Forbidden because of an OTK with "[[Lyrilusc - Independent Nightingale]]" (which is easily Summoned by "Instant Fusion"), where this card copies Nightingale's effect, which gives it 6000 ATK (5000 with its effect + 1000 from "Nightingale" itself), makes it unaffected by any other card effect, and enables it to inflict 5000 damage to your opponent once per turn, guaranteeing an OTK if it survives your opponent's turn. Differently from most other effect-copying monsters, Neptune does so permanently, making it particularly difficult to remove due to said immunity. Nothing that [[Crystal Wing Synchro Dragon|Crystal Wing]] or [[Kaiju]]s can't handle, but it's still terrifying to go up against otherwise. Can also be searched by [[King of the Feral Imps]].

| Activates a Field Spell directly from the Deck. Grants the user the ability to activate problematic Field Spells like [[Future Visions]] or [[Mystic Mine]] on their opponent's turn after having set up their own combo, adversely affecting their opponent's strategy. Can be searched by [[Trap Trick]] if run in multiples.
