How it works
Activate Mystic Sanctuary, a Forest and two other lands by tapping them, adding at least 3.
Activate Thaumatog's first ability four times by sacrificing Mystic Sanctuary, a Forest and two other lands, giving Thaumatog +4/+4 until end of turn.
Cast Splendid Reclamation by paying 3, returning all land cards from your graveyard to the battlefield untapped due to Archelos.
When each land enters the battlefield, Tatyova triggers that many times, and Mystic Sanctuary triggers once.
Resolve the Mystic Sanctuary trigger, putting Splendid Reclamation on top of your library from your graveyard.
Resolve the Tatyova triggers, causing you to draw that many cards and gain that much life.
Repeat.
If you control additional lands, you may sacrifice them as well to get additional mana and triggers.
This ingenious engine relies on Archelos, Lagoon Mystic keeping its vigilance state untapped so that all your returning lands bypass their usual delays and enter the battlefield ready for action. You feed your lands to Thaumatog to clear the graveyard, clearing the way for Splendid Reclamation to drag them all back from the dead in one fell swoop. Every time those lands flood back, Tatyova, Benthic Druid rewards your burgeoning board state with a steady stream of life and card draw. Amidst that tidal wave of landfalls, Mystic Sanctuary conveniently sneaks Splendid Reclamation right back to the top of your library, ensuring you have the spell ready to draw and cast again on the very next iteration.
