KeywordsProliferate

Why is this card good?

Karn's Bastion is one of the best proliferate sources in Commander because it's repeatable and costs you almost nothing on deckbuilding — it's a colorless land that taps for mana when you don't need the ability. The proliferate cost is steep at six total mana per activation, but it's a mana sink that scales every turn. The card shines in any +1/+1 counters deck (Atraxa, Ezuri, Hamza), planeswalker-heavy builds, and especially anything with infect or poison. It's also sneaky-good in superfriends and "counter soup" decks where each proliferate ticks loyalty, charge counters, and Saga chapters simultaneously. Atraxa decks love it as redundancy alongside Doubling Season effects. Don't run it in decks with no counter synergy — it's just a colorless land that enters fine but produces only generic mana and a dead ability. In two- or three-color decks needing reliable color, the colorless tap can stall hands. Only include it when you're actively building around counters.
