Zimone and Dina + Abundance + Intruder Alarm + Sporemound

Zimone and Dina

Abundance

Intruder Alarm

Sporemound

How it works

1. Activate Zimone and Dina by tapping it and sacrificing another creature, causing you to reveal cards from the top of your library until you reveal a land card, put it into your hand, then put the land onto the battlefield tapped, and repeat this process once if you control at least eight lands.
2. Sporemound triggers for each land that enters the battlefield this way.
3. Resolve the first Sporemound trigger, creating a 1/1 Saproling creature token.
4. When the Saproling enters the battlefield, Intruder Alarm triggers, untapping all creatures.
5. Repeat from step 3 for any remaining trigger(s), if needed.
6. Repeat from step 1.

This loop turns the simple act of sacrificing a creature into an engine that dumps every single land from your deck directly onto the battlefield. By replacing your standard draws with Abundance, you bypass actual card draw entirely to continuously feed land cards into Zimone and Dina's sacrifice-and-draw ability. Each land entering the battlefield triggers Sporemound to spawn a Saproling token, which immediately restarts the engine through Intruder Alarm's global untap ability.
