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 ingenious loop turns Shilgengar, Sire of Famine into a relentless engine by utilizing Yedora, Grave Gardener to immediately rescue your sacrificed creatures as lands. When you sacrifice Nervous Gardener to fuel Shilgengar's first ability, Yedora steps in to slide it right back onto the battlefield face-down as a Forest. From there, you simply tap that new land for mana to pay the disguise cost, turning Nervous Gardener face-up and triggering its search ability while setting it up to be sacrificed all over again.
