Text (SM): Choose three target nonenchantment permanents. Destroy one of them at random.
You cannot play this unless there are three legal targets. [D'Angelo 2008/05/17]
You randomly decide which one to destroy during resolution. There is no chance to react by any means (such as regenerating something) after this choice is made. You have to guess which one will be affected and plan beforehand. [Shadowmoor FAQ 2008/04/21]
If one target has become invalid before resolution, then randomly pick between the remaining two. If two targets are invalid before then, the remaining target is affected. [Shadowmoor FAQ 2008/04/21]
You can pick an indestructible target. If it gets randomly chosen, it simply won't be destroyed. [Shadowmoor FAQ 2008/04/21]
