Looks hilarious - I feel like there are still some optimizations that could be made to make it even less fun to play against still, but all in all good job.Lol.
I ran a version of this deck in the tourney on saturday, it's pretty strong and probably obnoxious as hell to play against, but it isn't as op as it looks. Also you forgot peaceful garden, that card wrecks a lot of creature based decks.
I have to stress how important contained parallel rift is for a mill deck because people are apparently unaware but not drawing it reduces your chances of winning by quite a lot.
any replacement for the painstone? :3
