Luke Cage loves this scheme to pull Knuckle Sandwich. He can use Knuckle Sandwich 5+ times to finish up a game. Going from 3 damage per event to 4 is a big damage boost. Keep Up the Pressure's 2 threat perfectly matches Luke's THW in solo. The Justice version is Generation X but it takes 3 threat instead of 2 and doesn't give a damage boost.

In multiplayer (or solo with Adam Warlock or Spider-woman), you may attach this to Live) Dangerously so that essentially everybody gains +1 hand size for a total cost of 2ER. This seems really very strong.

Outside of heroes with the giant trait like Wasp, i read this card as 3 ER: deal 3 dmg to the villain or 6 dmg to a minion. As long as you keep your hp high enough (generally 7+), this is an efficient big minion killer card.

This seems terrible. The first time you use it, you are even on cards and down whatever disadvantage the encounter brings. The second time, you are up 2 cards and down whatever disadvantage the two encounters brought - which could very easily be a trade you don't want to make.

I can see this being considered in a protection archangel deck (especially if that deck is packing symbiote suit). This essentially becomes trading 1 resource to cancel the acceleration icon on archangel.
