Summoning Station + Pitiless Plunderer + Umbral Collar Zealot

Summoning Station

Pitiless Plunderer

Umbral Collar Zealot

How it works

1. Activate Summoning Station by tapping it, creating a 2/2 Pincher creature token.
2. Activate Umbral Collar Zealot by sacrificing the Pincher.
3. When the Pincher dies, Pitiless Plunderer triggers, creating a Treasure token.
4. Resolve the Umbral Collar Zealot ability.
5. Activate the Treasure by tapping and sacrificing it, adding one mana of any color.
6. Summoning Station triggers, untapping it.
7. Repeat.

This loop relies on an elegant feedback loop between creature generation and artifact sacrifice. You begin by tapping Summoning Station to produce a 2/2 Pincher creature token, which you immediately sacrifice to Umbral Collar Zealot's ability to surveil. That sacrifice causes Pitiless Plunderer to trigger, creating a Treasure token, which is an artifact that immediately sends Summoning Station's passive untap ability into motion when it hits the graveyard. By sacrificing that Treasure for mana, you fuel the entire engine to repeat infinitely, generating endless death triggers, colored mana, and card selection.
