Karn is an unusual Planeswalker, to say the least. He has many significant weaknesses, but powerful and/or unique abilities, some of which work to turn his weaknesses into strengths, and all extremely useful. Being colorless, Karn can generally include [[card]]s of any [[color]] in his [[deck]]s, as long as they share a color with the [[event]] node on which he plays. He has high health and below average deck limits. His mana bonuses are perfectly balanced, but in total, as low as [[Origins]] Planeswalkers. His abilities are, added together, the cheapest in the game: his first is tied for cheapest, and the second and third are the cost of many Planeswalkers' first and second abilities.
