Spellsword

I love weapons.

Spellsword Doctor Strange floats above the battlefield, firing spells and grenades from above then swooping down to strike with his blade.

Jarnbjorn is the heart of the build and synergizes with all attack cards to allow an extra two damage to be dealt to an enemy of your choice. Enhanced Physique grants additional Strength resources to use Jarnbjorn's ability.

Dive Bomb does massive damage and can clear the board of cannon fodder.

Press the Advantage synergizes with Doctor Strange's constant stuns and confuses to draw cards. Ironheart and Spiritual Meditation provide for additional deck milling, turning over the player deck quickly.

Tenacity allows greater Invocation deck activation, the good Doctor's greatest asset.

Finally, Pulse Grenades allow for damage-on-demand (buffed by Jarnbjorn), which is great for getting rid of pesky Tough cards, and - perhaps more importantly - synergizes with Astral Projection to allow you to peek at, then discard, problematic Encounter cards.
