Maybe it's time that you add All Is Dust

I havn't tried the mentioned cards. Hour of Devastation seems like the best of the two.
The full spoiler for M21 is now up, and I'm definitely going to add Fiery Emancipation. I'm also considering Brash Taunter, but I'm debating if Stuffy Doll might actually be better in my build. Stuffy is easier to return, doesn't die to All Is Dust and is free to use. The only bonus Brash Taunter have is to potential deal a lot more damage per turn. Still think I'm going to get one and build a silly version of this deck with both Stuffy Dolls and Mogg Maniac.
