How it works
Activate Phyrexian Altar by sacrificing Nervous Gardener, adding one mana of any color.
When Nervous Gardener dies, Yedora triggers, returning Nervous Gardener from your graveyard to the battlefield face-down as a Forest land.
Activate Nervous Gardener by tapping it, adding .
Activate Nervous Gardener's disguise ability by paying , turning it face-up.
Nervous Gardener triggers, causing you to search your library for a land with a basic land type and put it into your hand.
Repeat.
This clever loop turns the cycle of life and death into a perpetual engine by letting Yedora, Grave Gardener continuously recycle our fallen allies as fresh timber. When we sacrifice Nervous Gardener to Phyrexian Altar for a splash of mana, Yedora steps in to return it straight to the battlefield face-down as a humble Forest land. From there, that newly sprouted land taps for green mana to immediately fund Nervous Gardener's disguise cost, turning it back face-up to trigger its search for a basic land type. By feeding the resulting mana right back into the Altar and the disguise ability, we generate infinite colored mana, endless deaths, and tutor every basic-typed land straight out of our library.
