This deck mixes the Shenaut archetype with the Pixie Mobius package (and a couple extra cards) to create a coherent, unexpected final turn bomb.
Naturally, She-Hulk and The Infinaut make a powerful combo when played in tandem. Magik allows these two on turn 7 if turn 6 is skipped, but Hope Summers allows this combo a turn sooner (provided something is played to her on turn 4). Moon Girl duplicates the She-Hulk for even more free Power. Sunspot soaks up any of that unused Energy.
Pixie and Mobius M. Mobius act as catalysts for this game plan, and Wasp, Hydra Bob (or Martyr), and Ant-Man cheapen our bigger cards. However, these cards also support the game plan otherwise. Ant-Man and Hydra Bob have 5 Power, and all three are cheap enough to trigger Hope Summers or keep the hand clear for Moon Girl.
Black Swan is the bow that ties it all together. Black Swan enables 1-Cost cards that have worsened in cost from Pixie to get out of your hand if you haven’t hit Mobius. Black Swan keeps 1-Costs out of hand for Moon Girl to hit bigger things and boosts Sunspot when you don’t need to pay for 1-Costs. And now, post-update, you can choose when to make your 1-Costs free! You can activate her on turn 5 and play all your 1-Costs alongside She-Hulk and Infinaut. Also, at a 2/3 statline, Black Swan curves out really well and makes Pixie a much stronger choice.
However, you may want to switch Black Swan for Caiera if you worry that Killmonger or Shang-Chi are prevalent threats.
From my experience, it is very easy to win games by surprise. Since the power dump is on the last turn, priority is often in the opponent’s hands. In these cases, Shang-Chi and Alioth are not threats. However, this deck is HIGHLY susceptible to Mobius M. Mobius- further meaning that cards like Super-Skrull, Loki, Cable, etc. are major threats. Also be cautious of cards like Legion that can turn off Limbo if you plan to skip turn 6.
