Relm's Sketching + Mystic Sanctuary + Sasaya, Orochi Ascendant // Sasaya's Essence + Experimental Frenzy

Relm's Sketching

Mystic Sanctuary

Sasaya, Orochi Ascendant // Sasaya's Essence

Experimental Frenzy

How it works

1. Cast Relm's Sketching from the top of your library by paying 2, creating a token copy of Mystic Sanctuary.
2. When the Mystic Sanctuary token enters the battlefield untapped, it triggers, putting Relm's Sketching from your graveyard onto the top of your library.
3. Activate the Mystic Sanctuary token by tapping it, adding .
4. Sasaya's Essence triggers, causing you to add for each other Mystic Sanctuary you control.
5. Activate the original Mystic Sanctuary by tapping it, adding .
6. Sasaya's Essence triggers, causing you to add for each other Mystic Sanctuary you control.
7. Repeat steps 1 through 4.

This intricate loop turns a single spell and a land into an engine of endless power, anchored by Sasaya's Essence—the flipped side of Sasaya, Orochi Ascendant—which dramatically multiplies the mana produced by your lands based on how many duplicates share their name. By using Relm's Sketching to continuously copy Mystic Sanctuary, every iteration lets the entering token's triggered ability place Relm's Sketching right back onto the top of your library. That positioning is crucial because Experimental Frenzy lets you cast spells directly from the top of your library while ignoring your hand, closing the loop so you can replay the spell endlessly. As you tap your growing army of Mystic Sanctuary tokens for blue mana, Sasaya's Essence turns each tap into a massive windfall of mana, fueling an infinite storm count and endless triggers.
