Is Azuki’s [On Play] like [On Play] in One Piece?
YesYes. One Piece’s [On Play] and Azuki’s [On Play] are the same timing: the effect happens when you play the card.
On Play in the Azuki TCG
[On Play] effects happen when the card is played: from your hand, or from your deck when an effect such as Skyreach Gate plays it. Bringing an entity through the Gate doesn’t trigger it again, and neither does any other move between zones. The card is already on the field when its own effect resolves.
The same
- Same name, same trigger: playing the card.
Different
- An Azuki entity can be played into the Alley, and its [On Play] still happens there, unless the card says it needs the Garden.
One Piece TCG: checked against the One Piece Card Game Comprehensive Rules. Azuki TCG: printed card text and the rules.
