Maha, Its Feathers Night + Elesh Norn, Grand Cenobite

Maha, Its Feathers Night

Elesh Norn, Grand Cenobite

How it works

1. All creatures your opponents control will have base toughness 0, and die as a state-based action due to having 0 toughness unless there is another effect increasing its toughness.
2. Whenever a creature enters the battlefield under an opponent's control, it will have base toughness 0, and die as a state-based action due to having 0 toughness unless there is another effect increasing its toughness.

This brutal combination completely locks opponents out of keeping any creatures on the battlefield by turning their toughness into zero. The magic happens because Maha, Its Feathers Night sets all creatures your opponents control to a base toughness of 1, which Elesh Norn, Grand Cenobite then reduces by an additional -2/-2. As a result, any creature your opponents currently control—or try to cast in the future—instantly meets a state-based death upon entering the battlefield unless bolstered by some external toughness-boosting effect.
