Lavinia LockoutTentative decklist for
Lavinia, Azorius Renegade. With her as your commander, the deck contains 3 different 1-card combos.
The first and best is
Knowledge Pool, which permanently prevents your opponents from playing spells for the rest of the game.
The second is
Omen Machine, which prevents your opponents from drawing or playing any spells that were not in their hand at the time of casting. (Not as solid a lock, but if they don’t have an answer in hand, it’s game)
The third is
Eye of the Storm, which, with Lavinia, prevents your opponents from casting Instant and Sorcery spells until the combo is broken. Not an immediate game winner, but worth including nonetheless.
