Phoenix is a crazy strong addition to the X-Men swarm strategy already enabled by Utopia, Uncanny X-Men, and "To Me, My X-Men!". She meets a strong efficiency baseline with her stats and easily adds about a resource worth of value with her enters play ability assuming there is another X-Men ally to target with at least 2 THW or ATK. There is no tempo penalty either as the ability comes with a ready to use that ally right away. Given the abundance of great allies in the game, I would only play her if I had an X-Men team deck, but in that deck she is one of the best allies you could possibly play.

Kid Omega is a staple-level ally with great utility regardless of deck composition. He meets acceptable efficiency if all he does is activate once and block, but the Response ability adds a really nice flexibility. It's a place to put an extra resource that might have gone to waste the turn you play him, and if there are multiple enemies or schemes out it is simply a strong, efficient ability. Kid Omega is an X-Men, which means he can be used in the "To Me, My X-Men!" archetype, which rewards allies with good enters-play abilities. He also fits into Uncanny X-Men decks, where he won't clog up your ally slots for too long given his low (yet efficiently-used) hp. He has Psionic synergies as well for a Power of the Mind / Psimitar strategy. A good baseline with high upside in certain decks or situations...an amazing card!

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.
