Hm BfZ seems interesting
Not entirely sure what devoid is about other than making target (color) creature do something
Ulamog is a game ender thats for sure and by the time you get him out your opponent usually has less than 20 so instant win
Green dosent seem to have as much big monsters and more low casting cost creatures this set
Blue has a card that is kinda OP Part the Waterveil lets blue get an entire extra turn meaning card advantage, more land, and a chance to play something big like ulamog.
Red is typical aggro and rush to victory with a few biggies in ther to end the game
Black seems to be focused on control and graveyard this set and less on lifesucking
It also seems to have alot of card draw meaning you could get overrun quick
White has life gain, weenies, enchantments, and lots of ways to beef creatures up.
