Patchwork Crawler + Trench Behemoth + Skyshroud Ranger

Patchwork Crawler

Trench Behemoth

Skyshroud Ranger

How it works

1. Activate Patchwork Crawler using Skyshroud Ranger's ability by tapping it, putting a land from your hand onto the battlefield.
2. If the land is mana-producing and enters the battlefield untapped, you may activate it by tapping it, adding at least 1.
3. Activate Patchwork Crawler using Trench Behemoth's ability by returning the land from the battlefield to your hand, untapping Patchwork Crawler.
4. Repeat.

This crafty loop turns Patchwork Crawler into a one-man engine by feeding it the stolen potential of its graveyard-bound peers. Once Trench Behemoth is safely exiled to grant its untap-and-bounce ability, and Skyshroud Ranger’s tap-to-play-a-land ability is absorbed, the Crawler can continuously drop a land from your hand, bounce it right back to hand to untap itself, and net a steady stream of infinite landfall triggers and mana (provided the land enters untapped).
