[[Karn, Scion of Urza]] is a colorless golem Planeswalker, introduced in April 2018, a month after before the release of the his origin card set, [[Rivals of IxalanDominaria]] card set. Being colorless, Karn can generally include cards of any color in his decks, as long as they share a color with the event node on which he plays.

His abilities have a minor {{Ability|Exile }} theme, including returning cards from exile to hand with a small mana boost, and {{Ability|fetch|fetching}} a card from the library and exiling others. His abilities can also permanently increase his mana bonuses, as well as create a strong golem {{Ability|Token}} whose powers depend on how many Supports you control.
