Soul Collector + Warstorm Surge + Marauding Raptor

Soul Collector

Warstorm Surge

Marauding Raptor

How it works

1. Cast Soul Collector by paying 2.
2. When Soul Collector enters the battlefield, Warstorm Surge and Marauding Raptor trigger.
3. Resolve the Warstorm Surge trigger, causing Soul Collector to deal damage to itself equal to its power.
4. Resolve the Marauding Raptor trigger, dealing 2 damage to Soul Collector.
5. Soul Collector dies as a state-based action due to having 0 or less toughness.
6. Soul Collector triggers, returning itself from your graveyard to the battlefield.
7. Repeat from step 2.

This clever loop turns Soul Collector's own replacement-style resurrection trick against itself by utilizing Marauding Raptor to immediately crush it upon arrival, aided by the cost reduction the Raptor provides. As Soul Collector enters the battlefield, Warstorm Surge adds lethal damage to the mix, ensuring the creature perishes so its own damage-based return trigger can immediately put it right back onto the battlefield.
