Return to Dust
From March of the Machine Commander set
Return to Dust
Instant
Exile target artifact or enchantment. If you cast this spell during your main phase, you may exile up to one other target artifact or enchantment.
Rulings
- Return to Dust can always target a second artifact or enchantment; it just won't exile it if it's not your main phase when you cast Return to Dust.
- If a spell or ability copies Return to Dust, the copy exiles only the first target artifact or enchantment. This is because the copy wasn't cast at all.
