Twin exarch combo deck that adds black to the color mix for early hand disruption in order to help protect the combo.

Dispel and Swerve help protect the combo as well. Swerve can redirect bolts, helixs and counter spells no matter what and if I control two or more creatures it can redirect path.

Faithless looting and sleight of hand help dig for combo pieces/counters.

The black also allows for different SB options like Leyline for living end/ goryos vengeance matchups. Teferi is strictly for matchups against control decks.
