Archelos, Lagoon Mystic + Mystic Sanctuary + Second Sunrise + Zuran Orb + Tatyova, Benthic Druid

Archelos, Lagoon Mystic

Mystic Sanctuary

Second Sunrise

Zuran Orb

Tatyova, Benthic Druid

How it works

1. Activate Mystic Sanctuary and two Plains by tapping them, adding at least 1.
2. Activate Zuran Orb three times by sacrificing Mystic Sanctuary and two Plains, causing you to gain 6 life.
3. Cast Second Sunrise by paying 1, returning all land cards put into your graveyard this turn 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 Second Sunrise 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 loop turns the battlefield into a self-sustaining engine by exploiting the static ability of Archelos, Lagoon Mystic, which ensures that lands entering the battlefield are forced to enter untapped. Because Mystic Sanctuary enters untapped this way, its landfall-like trigger fires to place Second Sunrise right back on top of your library, making it easy to redraw when Tatyova, Benthic Druid's card-drawing triggers resolve. Meanwhile, Zuran Orb provides the necessary sacrifice outlet to bin Mystic Sanctuary and your other lands so that Second Sunrise can return them all to the fray to repeat the entire cycle.
