MTG Salvation

12/1/2004 Dismantle targets only the artifact that will be destroyed. When Dismantle resolves, you choose which type of counters you want and choose an artifact you control to put them on.

12/1/2004 It doesn’t matter what kind of counters the destroyed artifact had on it, only how many. If an artifact had five bomb counters and two trap counters on it, that converts to seven +1/+1 counters or seven charge counters.

12/1/2004 You can put +1/+1 counters on a noncreature artifact. They won’t do anything unless the artifact becomes a creature, at which time they’ll add to the creature’s power and toughness.

7/1/2013 If the artifact regenerates or has indestructible, it won’t be destroyed, but you still put the appropriate number of counters onto an artifact you control.
