Scarlet Witch Agent of S.H.I.E.L.D.

This is the Scarlet Witch build that tipped the scales from solid to Top Tier for me. The deck was born from the Miles Starter deck that just didnt want to work with Miles but plays great here as Wanda has a lot of easy Chaos Magic ramp targets to get setup quickly.

Mulligan, Alter Ego and Spiritual Meditation Start

Search for any fast play ramp Helicarrier, Avengers Mansion, The Sorcerer Supreme and any double resources or Chaos Magic. Nick Fury is also a good dig card to find the treasure buried in your deck.

43 cards works fine for Scarlet

With the amount of looping through her deck she does 43 cards is great for me to cycle for the variant I want for the situation at hand, but for purists there are some easy cuts. Wiccan and Speed are there strictly for thematic purposes and Homeland Intervention at 3 copies is just over stocked and rarely played.

Basic Early Mid game Strategy

Land a piece of ramp up early. Set an Ally to mitigate damage and use Hex Bolts to control the board state.

Finish

Molecular Decay will finish the games for you. Just calculate when you want to flip the villain and cut lose.

Ally Selection

Agent Coulson is great at controlling a flip down by drawing Counterintelligence

Monica Chang is a great light chump blocker with thwart control - 4 counters on Surveillance Team is an amazing Thwart pinger.

War Machine is going to be a great midgame blocker for you that can do some heavy lifting

Dum Dum Dugan is suited mostly for the 2nd turn of the deck and the finish if you cant find a timely Molecular decay.
