New Ghost Council is sweet Limited Bomb, immune to sorcery speed removal is pretty sweet.
The new UB Legend Clone with Hexproof is pretty cool I guess. Reminds me of Sakashima the Imposter a bit.
Keyrune is a nice 2 mana damage per turn.

Ghost Council is a three turn clock which is super sweet.

niv got fatter, the council had a few members added to its incestual group(it was in guildpact!)
