Official Errata, This card should read as Hero Action: Remove "Go for Champions!" from the game - each Champion character in play cannot take damage until the end of the round." (Added "Remove "Go for Champions" from the game-")

Disguise was basically made for Justice Hulk. For that reason alone I love this card. The key thing to note is this can be triggered in both Hero and Alter-Ego forms. costs 1 resource. Removes 2 threat. This card can be a lifesaver in decks that flip often. You always have a chance to exhaust it and your identity, Especially nice if you don't need to heal yet have to flip for Obligations. You can do all the hero actions, flip over to alter-ego, discard the obligation and thwart for 2. So far the best heroes I see using this are : She-Hulk, Iron Man, Hulk and any hero that has less than 10 health. Definitely one of my favorite mutant-wave cards to test with older heroes.

Easily one of the best cards in the game. Sorcerer Supreme is 2 cost with a total of 4 playable heroes and +1 hand size. Endurance gives +3 health for 1 cost. So 3 Endurance gives 9 health, sorcerer supreme +1 card, for 5 cost so you add +1 to all powers and a additional health and no restriction for one encounter per phase. Definitely the best upgrade in game.

There are some heroes that play completely differently while they have a card from their kit in play vs not in play. Hawkeye with Hawkeye's Quiver is a prime example. Hawkeye's main problem lies in the fact that his Arrow events are what make him good, but his hero ability does nothing other than help you play your Arrow events, so his power level is up to the luck of the draw even more than most heroes. If you don't draw any Arrow events, then you might as well be playing with a blank identity; and if you draw too many of them, you'll just be spending them to pay for each other. But Hawkeye's Quiver solves both of those problems at once: you get to look for an Arrow event every turn you're in hero form, and you get to hang onto them separately from your hand for as long as you need until you play them. Overall a 100% high priority card to get into play any time you see it in your hand.
