Gretchen Titchwillow + Oboro Breezecaller + Gaea's Cradle

Gretchen Titchwillow

Oboro Breezecaller

Gaea's Cradle

How it works

1. Activate Gaea's Cradle by tapping it, adding at least .
2. Activate a land that enters untapped by tapping it, adding at least .
3. Activate Oboro Breezecaller by paying 2 and returning the land that taps for from the battlefield to your hand, untapping Gaea's Cradle.
4. Activate Gretchen by paying 2, causing you to draw a card and put the land from step 3 onto the battlefield.
5. Repeat.

This loop relies on the explosive mana generation of Gaea's Cradle—fueled by a board full of creatures—to drive a self-sustaining engine. With the green and blue mana provided by your lands, Oboro Breezecaller repeatedly bounces and replays a land to untap Gaea's Cradle, which conveniently triggers Gretchen Titchwillow's ability to draw cards and drop lands back onto the battlefield. By cycling the land in and out of your hand this way, Gretchen Titchwillow burns through your entire deck while generating limitless draw and landfall triggers.
