Leonin Relic-Warder + Rescue Skiff + Altar of Dementia

Leonin Relic-Warder

Rescue Skiff

Altar of Dementia

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 Altar of Dementia 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 Altar of Dementia ability from step 3.
8. Repeat from step 3.

This clever loop relies on a recursive exchange between Leonin Relic-Warder and Rescue Skiff to continuously cycle through the graveyard and battlefield. When Leonin Relic-Warder enters to exile Rescue Skiff, it leaves behind an opening to sacrifice itself to Altar of Dementia, which triggers Rescue Skiff to return from exile and immediately trigger its own ability to bring the cat back. Because Rescue Skiff is a Spacecraft that re-enters the battlefield fresh, it acts as an infinite recurrence engine for the Relic-Warder, allowing Altar of Dementia to mill your opponents out entirely through an endless cascade of creature sacrifices.
