Vhal, Candlekeep Researcher + Haunted One + Faces of the Past + Sage of Hours + Altar of Dementia

Vhal, Candlekeep Researcher

Haunted One

Faces of the Past

Sage of Hours

Altar of Dementia

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 Altar of Dementia 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 Altar of Dementia ability, causing target player to mill cards equal to Sage of Hours' power.
9. Repeat.

This intricate loop transforms Vhal, Candlekeep Researcher and Haunted One into an engine for infinite turns and mills. By tapping Vhal for restrictive colorless mana, you trigger Haunted One to grant your Humans and Wizards undying and a power boost, which conveniently pumps up the power of Sage of Hours to fuel Altar of Dementia's sacrifice trigger. When Sage of Hours dies, Faces of the Past untaps your entire crew—including Vhal—so you can repeat the process indefinitely.
