Metalcraft

Metalcraft is an ability word introduced in Scars of Mirrodin and gives a bonus to a permanent or a spell if its controller also controls three or more artifacts. It is exclusive to the Mirran faction. Metalcraft was featured as rules card 2 of 5 in the Scars of Mirrodin set and as rules card 2 of 5 in the Mirrodin Besieged set.

Most cards with Metalcraft are boosted with increases to power and/or toughness and/or keyword abilities for example *Auriok Sunchaser:

"Metalcraft — As long as you control three or more artifacts, Auriok Sunchaser gets +2/+2 and has flying."

Artifact cards with Metalcraft abilities are counted as one of the three required artifacts for the ability activation. Therefore, Chrome Steed becomes a 4/4 if you have two other artifacts in play.

Notable Metalcraft cards

• Rusted relic - Is a non-creature artifact that becomes a creature when you control three or more artifacts.
