Fastbond + Trenching Steed + Szarel, Genesis Shepherd

Fastbond

Trenching Steed

Szarel, Genesis Shepherd

How it works

1. Activate Trenching Steed by sacrificing a land.
2. Play the land from your graveyard.
3. Repeat.

This vintage combo creates a self-sustaining loop that leverages your graveyard as an extension of your hand. Fastbond removes the standard land-play restriction to let you play lands repeatedly, while Szarel, Genesis Shepherd allows you to pull those exact same lands right back out of your graveyard. The missing link is Trenching Steed, which provides the sacrifice outlet needed to put the lands back into the graveyard, successfully fueling the loop and triggering Szarel's sacrifice ability with every iteration.
