Protection from everything
If Progenitus would be put into a graveyard from anywhere, reveal Progenitus and shuffle it into its owner's library instead.
Progenitus is a five-color value pile: ramp hard, cheat or pay the 10 mana, and use a 10/10 protection-from-everything beater that can't be blocked, targeted, or killed. In practice the commander is just a colorless excuse to play the best cards in all five colors, leaning on ramp, fixing, and a powerful midrange-to-combo gameplan while Progenitus serves as an unstoppable backup wincon.
Prioritize fast, redundant ramp and fixing (Mana Crypt, Sol Ring, Mana Confluence, Prismatic Omen) so Progenitus and your bombs land early, and add cheat-into-play effects like Sneak Attack or Quicksilver Amulet to dodge the cost. Then layer in a tight combo finish—Thassa's Oracle, infinite-mana outlets, or extra-turn loops—so you don't rely solely on combat. Cut clunky high-cost cards that don't advance ramp, protection, or a fast win.
