This decks is created to have a very powerful curve starting on Turn 3. For this reason Quicksilver and Domino are in, and you must play both in the same location, followed by a 3-Cost card... If you have Okoye at the beginning, then she will be a better option to play than Domino.
Jubilee, and Doctor Doom are the key cards of the deck, but the others work perfectly well.
