How it works
Activate Bloodflow Connoisseur by sacrificing Sun Titan.
When Sun Titan dies, Minion's Return triggers, returning Sun Titan from your graveyard to the battlefield.
When Sun Titan enters, it triggers, returning Minion's Return from your graveyard to the battlefield attached to Sun Titan.
Resolve the Bloodflow Connoisseur ability.
Repeat.
This elegant recursive loop sets up an endless cycle of sacrifice and revival right on your battlefield. By using Bloodflow Connoisseur to devour Sun Titan, you trigger Minion's Return—which was enchanted to the Titan—to immediately bring it right back from the graveyard. That fresh entry lets Sun Titan pull Minion's Return back out of the graveyard and reattach itself, setting up the exact same sequence to be repeated indefinitely.
