Infinite Commander Casts with Geode Golem and Eldrazi Guacamole Tightrope

Step 1: Have Geode Golem on the battlefield and attack with it, dealing combat damage to a player.

Step 2: Use Geode Golem's ability to cast your commander, Commodore Guff, from the command zone without paying its mana cost.

Step 3: Use Commodore Guff's abilities to draw cards and generate advantage, or cast Tevesh Szat for additional draw and control.

Step 4: Sacrifice Eldrazi Guacamole Tightrope, then recast it from the graveyard by paying 2 life to enable continuous attacks with Geode Golem.

Step 5: Repeat the process to continuously cast your commanders and gain value from their abilities.
