FAQ
If this card's [Opponent's Turn] effect is activated by a [Trigger] effect such as "[Trigger] DON!! −1: Play this card.", which effect is activated first, the [On Play] effect of the Character played according to this [Trigger] or this [Opponent's Turn] effect?
In this case, the player with this Leader can choose the order in which the [On Play] effect of the Character played according to the [Trigger] effect and this [Opponent's Turn] effect are activated.
My Leader is [OP04-058 Crocodile] and I have 6 DON!! cards on my field when I activate this Character's [Trigger], return 2 DON!! cards from my field to my DON!! deck, and play this Character with 4 DON!! cards on my field. At this time, can I use this Character's [On Play] effect to draw 1 card?
Yes, you can. Your Leader's [Opponent's Turn] effect will have activated first, so you will have added 1 DON!! card, meaning you have 5 DON!! cards. Then, you will add 1 more DON!! card with this Character's [On Play] effect, so you will be able to draw 1 card.
