Soul Collector + Pandemonium + Aether Flash

Soul Collector

Pandemonium

Aether Flash

How it works

1. Cast Soul Collector by paying 3.
2. When Soul Collector enters the battlefield, Pandemonium and Aether Flash trigger.
3. Resolve the Pandemonium 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 clever loop transforms Soul Collector's unique delayed-trigger reanimation ability into a self-sustaining engine by letting the creature repeatedly destroy itself upon arrival. As Soul Collector enters the battlefield, it triggers both Pandemonium and Aether Flash, allowing Pandemonium to punch Soul Collector for its own power while Aether Flash swiftly finishes the job with 2 damage. Because Soul Collector was dealt damage by its own power during the turn, its replacement-style death trigger immediately brings it right back to the battlefield to do it all over again.
