Parallax Wave + Leonin Relic-Warder + Reveillark + Ashnod's Altar

Parallax Wave

Leonin Relic-Warder

Reveillark

Ashnod's Altar

How it works

1. Cast Leonin Relic-Warder by paying .
2. Leonin Relic-Warder enters the battlefield, triggering its first ability, targeting Parallax Wave.
3. Holding priority, activate Parallax Wave by removing a fade counter from it, exiling Reveillark.
4. Resolve the Leonin Relic-Warder trigger, exiling Parallax Wave.
5. Parallax Wave leaves the battlefield, triggering its ability.
6. Holding priority, activate Ashnod's Altar by sacrificing Leonin Relic-Warder, adding CC.
7. Leonin Relic-Warder leaves the battlefield, triggering its second ability, returning Parallax Wave from exile to the battlefield.
8. Resolve the Parallax Wave trigger from step 5, returning Reveillark from exile to the battlefield.
9. Reveillark enters the battlefield, returning Leonin Relic-Warder from your graveyard to the battlefield.
10. Repeat from step 2.

This exquisite loop sets up an endless cascade of triggers by exploiting the delayed-return mechanics of Parallax Wave and Leonin Relic-Warder. As Parallax Wave cycles its fade counters to temporarily banish Reveillark and Leonin Relic-Warder continuously targets the enchantment itself, Ashnod's Altar steps in to turn the rotating feline into a steady stream of colorless mana. Meanwhile, Reveillark's leaves-the-battlefield trigger ensures that Leonin Relic-Warder is relentlessly resurrected from the graveyard to keep the entire engine running indefinitely.
