Vhal, Candlekeep Researcher + Haunted One + Faces of the Past + Sage of Hours + Bloodflow Connoisseur

Vhal, Candlekeep Researcher

Haunted One

Faces of the Past

Sage of Hours

Bloodflow Connoisseur

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 Bloodflow Connoisseur 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 Bloodflow Connoisseur ability, putting a +1/+1 counter on it.
9. Repeat.

This clever loop turns Vhal, Candlekeep Researcher and Haunted One into a synergistic engine that repeatedly recycles your creatures, fueled by Vhal's massive toughness-based mana production. Whenever Vhal taps to generate colorless mana, Haunted One grants your shared-type creatures undying until end of turn, setting up the safety net for your sacrifice loops. You then sacrifice Sage of Hours to Bloodflow Connoisseur, triggering Faces of the Past to untap your board as Sage of Hours returns via undying with a +1/+1 counter. Because Bloodflow Connoisseur can keep growing while your creatures endlessly die and return, you can continuously churn through your sacrificial triggers and untaps to dominate the board.
