Each noncreature artifact you control is an artifact creature with power and toughness each equal to its converted mana cost.

Both part of the Legacy and an individual in his own right, the silver golem Karn is haunted by a single, terrible incident: while serving to protect the young Gerrard, Karn accidentally took the life of another. Wakened from years spent as a statue, the golem has vowed to never kill again as he rejoins Gerrard.
