Vhal, Candlekeep Researcher + Haunted One + Faces of the Past + Sage of Hours + Carrion Feeder

Vhal, Candlekeep Researcher

Haunted One

Faces of the Past

Sage of Hours

Carrion Feeder

How it works

1. Activate Vhal by tapping it, adding an amount of C equal to Vhal's toughness that cannot be spent to cast spells from your hand.
2. Haunted One triggers, causing Humans and Wizards you control to get +2/+0 and to gain undying until end of turn.
3. Activate Sage of Hours by removing all +1/+1 counters from it.
4. Activate Carrion Feeder by sacrificing Sage of Hours.
5. When Sage of Hours dies, its undying ability and Faces of the Past trigger.
6. Resolve the Sage of Hours trigger, returning it from your graveyard to the battlefield with a +1/+1 counter on it.
7. Resolve the Faces of the Past trigger, untapping all Humans and Wizards.
8. Resolve the Carrion Feeder ability, putting a +1/+1 counter on it.
9. Repeat.

This intricate loop turns Vhal, Candlekeep Researcher and Haunted One into a perpetual engine by leveraging shared creature types to bridge mana generation with recursive sacrifices. When Vhal taps for colorless mana, Haunted One grants your Humans and Wizards undying, which sets the stage for Sage of Hours and Carrion Feeder to cycle endlessly through the graveyard and battlefield. Every time Sage of Hours is sacrificed to Carrion Feeder and returns with undying, Faces of the Past triggers to untap your creatures, allowing Vhal to tap again and repeat the cycle indefinitely.
