Keep using Scarlet Witch until it flips worldship. They'll never see it coming.
Agent 13 - for a 1/229 (as of Feb 2023) chance of generating an extra Scarlet witch
M'Baku - Obligatory inclusion as he's the strongest cards in current meta. Honestly needs to be toned down to a bit, maybe make him cost 15 energy.
Ebony maw - Win Adam Warlock lane to draw Scarlet Witch
Adam Warlock - Draw Scarlet witch
Beast - Pick up Scarlet and use her again (backup plan)
Mystique - Copy Wong and play Scarlet on turn 5
Jubilee - Try pulling Scarlet from your deck if she's not in your hand
Wong - Multiply the triggers on Scarlet for a greater chance to hit Worldship
Absorbing man - Copy Scarlet witch for additional activations
Moongirl - Double Scarlet witches in hand and/or scarlet witch combo cards in hand
Odin - Trigger Scarlet witch again, preferably on Wong lane
