Leonin Relic-Warder + Rescue Skiff + Thermopod

Leonin Relic-Warder

Rescue Skiff

Thermopod

How it works

1. Cast Leonin Relic-Warder by paying .
2. When Leonin Relic-Warder enters, its first ability triggers, exiling Rescue Skiff.
3. Activate Thermopod by sacrificing Leonin Relic-Warder.
4. When Leonin Relic-Warder dies, its second ability triggers, returning Rescue Skiff from exile to the battlefield.
5. When Rescue Skiff enters, it triggers, returning Leonin Relic-Warder from your graveyard to the battlefield.
6. When Leonin Relic-Warder enters, its first ability triggers, exiling Rescue Skiff.
7. Repeat from step 3.

This ingenious loop centers around an infinite exchange between Leonin Relic-Warder and Rescue Skiff. When Leonin Relic-Warder enters the battlefield, its entry trigger exiles Rescue Skiff, which in turn immediately triggers Rescue Skiff's ability to pull Leonin Relic-Warder right back out of your graveyard as it enters. Meanwhile, Thermopod sits in play waiting to capitalize on this revolving door, happily turning every iteration of Leonin Relic-Warder into a sacrifice for red mana. Because Rescue Skiff continuously revives the cat and the cat continuously exiles the spacecraft, you get an endless cycle of enters-the-battlefield and death triggers fueled entirely by the mana-generating sacrifice outlet of Thermopod.
