"Find me cards equivalent to: Karn's Bastion"

Equivalent cards to Karn's Bastion with similar colorless land and proliferate or counter-manipulation effects include:

  • Karn's Bastion (your original card)
  • Opal Palace (adds any color, sometimes used in colorless decks)
  • Forge of Heroes (gives counter, less flexible)
  • Gavony Township (not colorless, but similar effect for counters, green-white)
  • Contagion Clasp/Contagion Engine (colorless but are artifacts, not lands, and proliferate)

No other land is strictly equivalent to Karn's Bastion in being colorless, producing {C}, and proliferating. Karn's Bastion is unique for colorless proliferate on a land.

    Abilities/Keywords

    Proliferate

    Rules

  • Contagion Clasp's first ability is mandatory. If you're the only player who controls a creature, you must target one of them.
  • An ability that triggers "Whenever you proliferate" triggers even if you chose no permanents or players while doing so.
  • If a permanent ever has both +1/+1 counters and -1/-1 counters on it at the same time, they're removed in pairs as a state-based action so that the permanent has only one of those kinds of counters on it.
  • If a player or permanent has more than one kind of counter on it, and you choose for it to get additional counters, it must get one of each kind of counter it already has. You can't have it get just one kind of counter it already has and not the others.
  • Players can respond to a spell or ability whose effect includes proliferating. Once that spell or ability starts to resolve, however, and its controller chooses which permanents and players will get new counters, it's too late for anyone to respond.
  • To proliferate, you can choose any permanent that has a counter, including ones controlled by opponents. You can choose any player who has a counter, including opponents. You can't choose cards in any zone other than the battlefield, even if they have counters on them.
  • You don't have to choose every permanent or player that has a counter, only the ones you want to add another counter to. Since "any number" includes zero, you don't have to choose any permanents at all, and you don't have to choose any players at all.

    Proliferate

    Rules

  • As Contagion Engine's activated ability resolves, you'll complete an entire proliferate action, then you'll complete a second proliferate action. You may choose different players and/or permanents, or different counters on those permanents, when you proliferate the second time.
  • Players can't respond between the first and the second proliferate actions.
  • An ability that triggers "Whenever you proliferate" triggers even if you chose no permanents or players while doing so.
  • If a permanent ever has both +1/+1 counters and -1/-1 counters on it at the same time, they're removed in pairs as a state-based action so that the permanent has only one of those kinds of counters on it.

  • If Opal Palace's last ability produces two mana (most likely due to Mana Reflection) and you spend them to cast a commander, that commander enters with two counters for each time it's been cast from the command zone this game.
  • If you don't have a commander, Opal Palace's last ability produces no mana.
  • If you have two commanders, the last ability adds one mana of any color in their combined color identities.
  • If your commander is a card that has no colors in its color identity, Opal Palace's last ability produces no mana. It doesn't produce {C}.
  • The "number of times it's been cast from the command zone" includes the most recent time. For example, the first time you cast your commander from the command zone in a game, if you spent mana from Opal Palace's last ability to do so, it will enter the battlefield with a +1/+1 counter.
