Embiggen is a 2 cost upgrade for Ms Marvel that reads:
Hero Interrupt: When you play an Attack event, exhaust Embiggen! → increase the amount of damage that event deals by 2.
Melee is a 3 cost Aggression attack event that reads:
Hero Action (attack): Deal 3 damage to an enemy. Deal 3 damage to another enemy.
So you can essentially do 5 / 5 using Embiggen on two enemies, bring it back into your hand with Ms Marvel's response and then possibly play it again for another 3 to each enemy. Seems overpowered, no? You could possibly play the first Melee for 1 resource using Nakia's ability, flipping to Ms Marvel and using Biokinetic Polymer suit and still have plenty of resources to get the Melee out one more time for 3 resources. Could be 16 damage split between 4 enemies at a cost of 4 total resources if you board state is set up correctly.
