Felidar Guardian + Vesperlark + Bloodflow Connoisseur

Felidar Guardian

Vesperlark

Bloodflow Connoisseur

How it works

1. Cast Felidar Guardian by paying 3.
2. When Felidar Guardian enters the battlefield, it triggers, targeting Vesperlark.
3. Holding priority, activate Bloodflow Connoisseur by sacrificing Felidar Guardian.
4. Resolve the Felidar Guardian trigger, blinking Vesperlark.
5. When Vesperlark leaves the battlefield, it triggers, returning Felidar Guardian from your graveyard to the battlefield.
6. Repeat from step 2.

This ingenious loop turns a fragile elemental into a perpetual motion machine by exploiting Vesperlark's leaves-the-battlefield trigger. When Felidar Guardian enters the battlefield, its blink ability targets Vesperlark, but sacrificing Felidar Guardian to Bloodflow Connoisseur in response sends the cat straight to the graveyard—triggering Vesperlark to pull it right back out. This cycle constantly resets the board state, feeding Bloodflow Connoisseur an endless stream of sacrifices to grow infinitely large while generating infinite entry, exit, and death triggers.
