Experiment Kraj + Trench Behemoth + Skyshroud Ranger

Experiment Kraj

Trench Behemoth

Skyshroud Ranger

How it works

1. Activate Experiment Kraj 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 Experiment Kraj using Trench Behemoth's ability by returning the land from the battlefield to your hand, untapping Experiment Kraj.
4. Repeat.

This ingenious loop relies on Experiment Kraj as the ultimate shapeshifter, soaking up the activated abilities of its peers like a biological sponge. By absorbing Skyshroud Ranger's tapping power, Experiment Kraj can repeatedly dump lands from your hand straight onto the battlefield to fuel your engine. Then, Trench Behemoth steps in to pick that very same land right back up into your hand while effortlessly untapping Experiment Kraj in the process. Because every cycle drops and bounces a land, you generate endless landfall triggers and can continuously tap any untapped lands for infinite mana.
