Yedora, Grave Gardener + Granite Witness + Skirk Alarmist + Krark-Clan Ironworks

Yedora, Grave Gardener

Granite Witness

Skirk Alarmist

Krark-Clan Ironworks

How it works

1. Activate Krark-Clan Ironworks by sacrificing Granite Witness, adding CC.
2. When Granite Witness dies, Yedora triggers, returning Granite Witness from your graveyard to the battlefield face-down as a Forest land.
3. Activate Granite Witness by tapping it, adding .
4. Activate Skirk Alarmist by tapping it, turning Granite Witness face-up.
5. Granite Witness triggers, untapping Skirk Alarmist.
6. Repeat.

This clever loop turns the cycle of life, death, and morphing into an infinite engine powered by Yedora, Grave Gardener, which quietly ensures that any nontoken creature you control that dies immediately returns to the battlefield as a face-down Forest land. You can sacrifice that very land—masquerading as Granite Witness—to Krark-Clan Ironworks for colorless mana, which then triggers Yedora to bring it right back to the field to be played as a mana source that taps for green. Skirk Alarmist plays its part by tapping to flip Granite Witness face-up using its disguise ability, which in turn triggers Granite Witness's own ability to untap Skirk Alarmist and ready it for the next iteration.
