Majin Destruction 
				Useful, I suppose.  At least in 
				Focused, there is not alot of speed removal for setups, and the 
				current strong decks (Orange Ally), uses alot of setups, so this 
				can be a helpful sweeper.  The fact that it is a rather big 
				energy, and not an event, is nice as well, as it cannot be 
				sphered like some of this set's other mass removal cards.  Worth 
				the one slot it will get in Focused, though probably not 3, if 
				you are running it's style.
				It's probably a little helpful in 
				Expanded, as ball decks tend to have a huge load of setups 
				(mainly DBall search and combat enders), and wiping them all 
				from the board in one swipe is never bad.  In this case, it is 
				worthwhile to run as many of this as you can, though in the 
				Sensei deck, methinks.
				Average in Limited.  Setups can 
				help, but they are not game-breakers, either.  It still shoots 
				to the dome, though.
				Focused 4/5
				Expanded 3/5
				Sealed 3/5
