Dualcaster Mage + Fake Your Own Death + Bloodflow Connoisseur

Dualcaster Mage

Fake Your Own Death

Bloodflow Connoisseur

How it works

1. Cast Fake Your Own Death by paying 1, targeting any creature.
2. Holding priority, cast Dualcaster Mage by paying 1.
3. When Dualcaster Mage enters the battlefield, it triggers, copying Fake Your Own Death, targeting Dualcaster Mage.
4. Resolve the copy of Fake Your Own Death.
5. Holding priority, activate Bloodflow Connoisseur by sacrificing Dualcaster Mage.
6. When Dualcaster Mage dies, it triggers, returning itself from your graveyard to the battlefield and creating a Treasure token.
7. Repeat from step 3.
8. Resolve all Bloodflow Connoisseur abilities, putting that many +1/+1 counters on it.

This loop sets up an infinitely recurring cycle by turning Dualcaster Mage's spell-copying entry trigger into a self-sustaining engine. With Fake Your Own Death granting the Mage an undying-style safety net that also spawns a Treasure token upon death, you can safely sacrifice the Mage to Bloodflow Connoisseur. The resulting death trigger returns the Mage to the battlefield, where its fresh entry trigger copies Fake Your Own Death yet again to perpetuate the loop. Meanwhile, Bloodflow Connoisseur happily grows with endless +1/+1 counters while the Treasures fuel your mana needs for any additional spells you wish to cast.
