Leonin Relic-Warder + Enchanted Evening

Leonin Relic-Warder

Enchanted Evening

How it works

1. Cast Leonin Relic-Warder by paying .
2. When Leonin Relic-Warder enters the battlefield, its first ability triggers, exiling itself.
3. When Leonin Relic-Warder leaves the battlefield, its second ability triggers, returning itself from exile to the battlefield.
4. Repeat from step 2.

This clever loop hinges entirely on Enchanted Evening's static ability, which transforms every single permanent on the battlefield into an enchantment alongside its other types. Once this global enchantment is active, casting Leonin Relic-Warder allows its enters-the-battlefield trigger to target itself, since it is now a valid enchantment. When the Leonin Relic-Warder is exiled by its own effect, it immediately leaves the battlefield, triggering its second ability to return itself right back to the battlefield. This creates a perpetual cycle of entering and leaving the battlefield, generating infinite triggers without needing any outside intervention.
