Dualcaster Mage + Bloodflow Connoisseur + Behold the Sinister Six!

Dualcaster Mage

Bloodflow Connoisseur

Behold the Sinister Six!

How it works

1. Cast Behold the Sinister Six! by paying its mana cost
2. Holding priority, cast Dualcaster Mage by paying its mana cost.
3. When Dualcaster Mage enters, it triggers, targeting Behold the Sinister Six!.
4. Holding priority, activate Bloodflow Connoisseur by sacrificing Dualcaster Mage.
5. Resolve the Dualcaster Mage trigger, copying Behold the Sinister Six!, with the copy targeting Dualcaster Mage
6. Resolve the Behold the Sinister Six! copy, returning Dualcaster Mage from your graveyard to the battlefield.
7. Repeat from step 3.

This elegant loop transforms Behold the Sinister Six! into a miraculous engine for endless recursion, pulling Dualcaster Mage right back from the graveyard each time it enters and copies the massive spell. Because Behold the Sinister Six! can target up to six creatures with different names, your graveyard needs just enough diversity to get the chain started, letting Dualcaster Mage continuously target the original spell. Meanwhile, Bloodflow Connoisseur acts as the necessary sacrifice outlet, neatly sweeping away the mage to fuel the loop while piling on an infinite number of +1/+1 counters.
