At the start of your end phase, select an enemy follower on the field and deal it 2 damage.
QI have 6 max play points. If I choose option 1 for Neo Universe's On Evolve ability and discard Katsuragi Ace, can I then summon Katsuragi Ace with its "When this card is discarded" ability?
AYes. Katsuragi Ace's ability resolves after Neo Universe's On Evolve ability finishes resolving, so you will have gained 1 max play point and entered Overflow.
