Once per turn vs other games
[Once/Turn] effects work once a turn, per card. Another copy has its own use, and a card that leaves the field and comes back is a new card that can use it again.
Is it like…
Once per turn (soft and hard) in Yu-Gi-Oh!Partly
Partly. Azuki [Once/Turn] works like Yu-Gi-Oh!’s soft once per turn: each copy gets its own use. Yu-Gi-Oh!’s hard once per turn (“You can only use this effect of [card name] once per turn”) counts every copy together; the Azuki TCG has nothing like that.
What’s the same and what’s different[Once Per Turn] in One Piece TCGYes
Yes. One Piece’s [Once Per Turn] and Azuki’s [Once/Turn] both let each card use the effect once a turn.
