Strange's Spell Spam

Sorcerer Supreme Stephen Strange spams spells splendidly. (Ready as much as possible to spam invocations with Dr. Strange's Spell Mastery action.)

Cloak of Levitation and Stick-To-Itiveness gives 2 extra readies every turn. (Stick-To-Itiveness will typically be paid with 1 of the wild resource generators: The Eye of Agamotto, Quincarrier, or Bloodgem if that's the 1st available and the HP hit is worth the ready)

Make Wong an Honorary Avenger to have up to 4 Avenger allies to use with Earth's Mightiest Heroes when Avengers Tower is in play. Besides readying Strange, Earth's Mightiest Heroes can also ready Wong when needed to skip over more invocations or to heal Strange enough to get more resources out of the 'Pool resource cards.

With up to 4 allies out and Strange himself, there's a solid group of targets for Seven Rings of Raggadorr even in solo.

Mulligan can draw a new hand after paying the costs of Spell Mastery (potentially paying for multiple spells with readies) since those invocation events aren't being played.

Healing Factor keeps Strange healthy for the 'Pool resource cards to be double or triple resources.

Strange can get even more readies from teammates for more spell spam when playing multiplayer. Check out Nebula's S.C.A.R.S. for a deck designed to maximize readies for Avenger heroes.
