Athreos, Shroud-Veiled + Blue, Loyal Raptor + Umbral Collar Zealot

Athreos, Shroud-Veiled

Blue, Loyal Raptor

Umbral Collar Zealot

How it works

1. Cast the Dinosaur in your hand by paying its mana cost. It will enter with a coin counter due to Blue.
2. Activate Umbral Collar Zealot by sacrificing the Dinosaur.
3. When the Dinosaur dies, Athreos's second ability triggers, returning the Dinosaur from your graveyard to the battlefield. It will enter with a coin counter due to Blue.
4. Resolve the Umbral Collar Zealot ability.
5. Repeat from step 2.

This loop is a masterclass in turning a single piece of setup into a relentless engine, starting with Blue, Loyal Raptor pre-marking your creatures with coin counters as they hit the battlefield. Once your Dinosaur is in play, you feed it to Umbral Collar Zealot's sacrifice ability to trigger an endless cascade of surveil actions. Because the Dinosaur dies with a coin counter, Athreos, Shroud-Veiled steps in with his glorious triggered ability to instantly return it to your side of the battlefield—right in time for Blue, Loyal Raptor to ensure it enters with another coin counter, ready to be sacrificed all over again.
