Scarlet Witch Controlling The Villain's Activation

The idea of this deck is to mitigate the villain's damage and controlling the encounter that you will get.

Black Widow and Get Behind Me! are great to prevent the treachery card you will get while Heimdall and Warp Reality will help to prevent any strong encounter card (attachment / side scheme). To help with Black Widow's interrupt resource i use Quincarrier, to summon Heimdall you can use the Chaos Magic.

You can also give a lot of stun status on the enemy with Iron Fist, Never Back Down and Hex Bolt.

Getting attacked by the enemy can be reduced by Desperate Defense, Never Back Down and Magic Shield so i think that she's pretty hard to pinned down in hero mode (you can also use her ability to redraw any boost card or use the Scarlet Witch's Crest to lower the damage.)

Deft Focus is good to have for Hex Bolt and Warp Reality, while they're not that expensive and only 5 of them are there, i think it's important to lessen the cost of your most epic spell, hex bolt is a great diverse card you can use along with Helicarrier or Quincarrier to damage, thwart or giving a character status.

I'm also adding Nerves of Steel so your defense cards (get behind me and never back down) are free to play. Basically with the upgrades most of your card will be very cheap to use.

With Wanda's alter ego action you can find some decent preparation card early, i suggest to get either one of the Supports, the The Sorcerer Supreme, Scarlet Witch's Crest, Deft Focus, Nerves of Steel or Unflappable. Getting Warp Reality and Chaos Magic will be great as well. Discard any defense event early on.
