Q
I set 2 character cards in the set zone while preparing for the turn.
If the character card that doesn't go into the battle zone has an effect, does it take effect?
A
No, it doesn't.
When you set 2 character cards, the one in set zone A is swapped in, and only the clock of the one in set zone B counts that turn. Its effect doesn't take effect even if its power cost is met, and it's put in the power charger or abyss at the end of the turn.
