Leonin Relic-Warder + Rescue Skiff + Viscera Seer

Leonin Relic-Warder

Rescue Skiff

Viscera Seer

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 Viscera Seer 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. Resolve the Viscera Seer ability from step 3.
8. Repeat from step 3.

This clever loop sets up an infinite cycle by having Leonin Relic-Warder and Rescue Skiff continuously rescue each other from exile and the graveyard. When Leonin Relic-Warder enters to exile the Spacecraft, you sacrifice the cat to Viscera Seer, which triggers the Rescue Skiff to return to the battlefield and immediately bring the Leonin Relic-Warder right back along with it. Because Viscera Seer's sacrifice outlet lets you repeat this dance endlessly without ever needing to cast your spells again, you can effortlessly churn through your entire library while generating infinite artifact and creature triggers.
