Dualcaster Mage + Bloodflow Connoisseur + Abnormal Endurance

Dualcaster Mage

Bloodflow Connoisseur

Abnormal Endurance

How it works

1. Cast Abnormal Endurance by paying its mana cost.
2. Holding priority, cast Dualcaster Mage by paying its mana cost.
3. When Dualcaster Mage enters, it triggers, copying Abnormal Endurance, with the copy targeting Dualcaster Mage.
4. Resolve the copy of Abnormal Endurance.
5. Holding priority, activate Bloodflow Connoisseur by sacrificing Dualcaster Mage.
6. When Dualcaster Mage dies, it triggers, returning it from your graveyard to the battlefield.
7. Repeat from step 3.
8. Resolve all Bloodflow Connoisseur abilities from step 5.

This clever loop creates an unstoppable cycle by turning Dualcaster Mage into a self-recurring engine for sacrifice and spell copying. By casting Abnormal Endurance and responding with Dualcaster Mage to copy it, you set up a protection spell that triggers every time the Mage hits the graveyard. From there, Bloodflow Connoisseur steps in as the designated executioner, devouring Dualcaster Mage for a +1/+1 counter so that Abnormal Endurance's delayed trigger can immediately return the Mage to the battlefield to copy the spell all over again.
