Instant, 2WW (4) Remove target artifact or enchantment from the game. If you played this spell during your main phase, you may remove up to one other target artifact or enchantment from the game. Some timelines forever fray, branch, and intermingle. Others end abruptly.

9/25/2006: Regardless of when Return to Dust is played, its controller may choose one target or two targets. It can always be played even if there's only one legal target. If it's played at a time other than its controller's main phase and a second target is chosen, nothing will happen to that target.
