Vizier of Remedies

Glen Elendra Archmage

Yahenni, Undying Partisan

How it works

1. Activate Yahenni by sacrificing Glen Elendra Archmage.
2. When Glen Elendra Archmage dies, its persist ability triggers, returning it from your graveyard to the battlefield without a -1/-1 counter on it due to Vizier of Remedies.
3. Resolve the Yahenni ability
4. Repeat.

This loop turns Glen Elendra Archmage into an endlessly reusable counter-spell engine by exploiting the clever math of Vizier of Remedies. Whenever you feed the Archmage to Yahenni, Undying Partisan, persist tries to bring her back with a -1/-1 counter, but the Vizier steps in to reduce that amount to zero—leaving her pristine and ready to persist again. Because Yahenni's sacrifice ability requires no mana, this setup lets you repeatedly deny your opponents' noncreature spells while generating an endless stream of sacrifice, death, and entry triggers to fuel your victory.
