How it works

1. Activate Parallax Wave by removing a fade counter from it, exiling Reveillark.
2. When Reveillark leaves the battlefield, it triggers, returning Leonin Relic-Warder from your graveyard to the battlefield.
3. When Leonin Relic-Warder enters the battlefield, its first ability triggers, exiling Parallax Wave.
4. When Parallax Wave leaves the battlefield, it triggers.
5. Holding priority, activate Viscera Seer by sacrificing Leonin Relic-Warder.
6. When Leonin Relic-Warder leaves the battlefield, its second ability triggers, returning Parallax Wave from exile to the battlefield.
7. Resolve the Viscera Seer ability, causing you to scry 1.
8. Resolve the Parallax Wave trigger from step 4, returning Reveillark from exile to the battlefield.
9. Repeat.
