Fastbond + Crucible of Worlds + Troubled Healer

Fastbond

Crucible of Worlds

Troubled Healer

How it works

1. Activate Troubled Healer by sacrificing a land.
2. Play the land from your graveyard.
3. Repeat.

This Vintage-legal loop turns self-inflicted pain into an engine by letting **Fastbond** bypass normal land-play limits so you can keep dropping the same land over and over. You use **Troubled Healer** to sacrifice that land to its own ability, which conveniently prevents the damage **Fastbond** would deal to you for playing a non-initial land. Once the land hits your graveyard, **Crucible of Worlds** steps in to let you play it right back out, resetting the cycle for infinite landfall triggers and endless mana from any untapped lands you control.
