How it works
Activate Mystic Sanctuary and two Plains by tapping them, adding at least 1.
Activate Lithatog's second ability three times by sacrificing Mystic Sanctuary and two Plains, giving Lithatog +3/+3 until end of turn.
Cast Second Sunrise by paying 1, returning all land cards put into your graveyard this turn to the battlefield untapped due to Archelos.
When each land enters the battlefield, Aesi triggers that many times, and Mystic Sanctuary triggers once.
Resolve the Mystic Sanctuary trigger, putting Second Sunrise on top of your library from your graveyard.
Resolve the Aesi triggers, causing you to draw that many cards.
Repeat.
If you control additional lands, you may sacrifice them as well to get additional mana and triggers.
