Emeria Shepherd + Wormfang Newt + Altar of Dementia

Emeria Shepherd

Wormfang Newt

Altar of Dementia

How it works

1. Activate Altar of Dementia by sacrificing Wormfang Newt.
2. When Wormfang Newt dies, its second ability triggers, returning a Plains from exile to the battlefield.
3. When the Plains enters the battlefield, Emeria Shepherd triggers.
4. Holding priority, activate the Plains by tapping it, adding .
5. Resolve the Emeria Shepherd trigger, returning Wormfang Newt from your graveyard to the battlefield.
6. When Wormfang Newt enters the battlefield, its first ability triggers, exiling a Plains.
7. Resolve the Altar of Dementia ability from step 1, causing target player to mill cards equal to Wormfang Newt's power.
8. Repeat.

This clever loop relies on the brilliant recursive engine of Emeria Shepherd together with a Plains to bypass going to the hand, slipping nonland permanents straight back onto the battlefield instead. By feeding Wormfang Newt to the Altar of Dementia, you trigger the Newt's departure to rescue the very Plains needed to fuel the Shepherd's landfall ability. As the returning Plains re-enters, it triggers the Shepherd to pull Wormfang Newt right back out of the graveyard, resetting the cycle while generating an endless supply of white mana, death triggers, and milled cards.
