It's Day of Judgment, with the caveat that it can show up when you don't want it to, and you can't stop it when it does (unless you have indestructible creatures or a Stifle handy). I'd be hesitant to run this in my planar deck.

The saving grace of this card is the deck it comes in. This deck is loaded with Umbra's, which will save your creatures. So all of your opponent's creatures die, and you lose all non-Umbra'd creatures and all umbra's. 4/5
