Archelos, Lagoon Mystic + Mystic Sanctuary + Splendid Reclamation + Spitting Spider + Tatyova, Benthic Druid

Archelos, Lagoon Mystic

Mystic Sanctuary

Splendid Reclamation

Spitting Spider

Tatyova, Benthic Druid

How it works

1. Activate Mystic Sanctuary, a Forest and two other lands by tapping them, adding at least 3.
2. Activate Spitting Spider four times by sacrificing Mystic Sanctuary, a Forest and two other lands, dealing 4 damage to each creature with flying.
3. Cast Splendid Reclamation by paying 3, returning all land cards from your graveyard to the battlefield untapped due to Archelos.
4. When each land enters the battlefield, Tatyova triggers that many times, and Mystic Sanctuary triggers once.
5. Resolve the Mystic Sanctuary trigger, putting Splendid Reclamation on top of your library from your graveyard.
6. Resolve the Tatyova triggers, causing you to draw that many cards and gain that much life.
7. Repeat.
8. If you control additional lands, you may sacrifice them as well to get additional mana and triggers.

This looping marvel centers on Archelos, Lagoon Mystic, whose static ability ensures that when your lands return to the battlefield, they arrive completely untapped instead of tapped. By casting Splendid Reclamation, you flood the board with every land resting in your graveyard, triggering Tatyova, Benthic Druid repeatedly to gain life and draw through your entire deck. Among those returned lands is Mystic Sanctuary, whose own triggered ability conveniently places Splendid Reclamation right back on top of your library to be drawn. Finally, Spitting Spider serves as a brilliant sacrifice outlet to feed the loop by binning your lands back into the graveyard while clearing out enemy flyers, allowing you to repeat the cycle infinitely.
