Soul Collector + Warstorm Surge + Aether Flash

Soul Collector

Warstorm Surge

Aether Flash

How it works

1. Cast Soul Collector by paying 3.
2. When Soul Collector enters the battlefield, Warstorm Surge and Aether Flash trigger.
3. Resolve the Warstorm Surge trigger, causing Soul Collector to deal damage to itself equal to its power.
4. Resolve the Aether Flash 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 elegant recursive loop relies on Soul Collector entering the battlefield and immediately self-destructing via the combined force of Warstorm Surge and Aether Flash. Because Warstorm Surge measures Soul Collector's power and deals that damage back to it—alongside Aether Flash's passive damage dealing—the creature instantly drops to zero toughness and perishes. However, Soul Collector's own triggered ability recognizes the damage it dealt to itself and promptly returns it to the battlefield, setting the stage to loop the entire process infinitely.
