The Doctor, The Witch, and the Ward

Scarlet Witch ally in Justice sings a siren song. Her stat line 2/2/3 at 2 cost seems too good to be true. The true cost is possibly revealing another treachery card. The good Doctor can negate the treachery effect using Protective Ward. This interaction was the kernel for creating this deck.

Thematically it then follows to include those choice Mystic-only cards: Sorcerer Supreme, Spiritual Meditation, and Bloodgem.

Since the Bloodgem feeds off of the Sorcerer Supreme's health, he might occasionally recover by Making an Entrance.

Cloak of Levitation gives Doctor Strange the Aerial trait, so now he can be Everywhere All at Once. Might as well Even the Odds while he's at it.

Scarlet Witch is joined by other Avengers Justice allies since she is dual-traited. Wong becoming an Honorary Avenger opens an additional ally slot with Avengers Tower. An additional ally can sit in Avengers Compound until space is available for them to enter the field.
