I think that Supreme Archaeology would have home in this deck simply because you are trying to draw into your combo of Defile, Knife Juggler, Grim Patron, and Deathspeaker and any reduction in cost is helpful. But I don't have it... yet...

Stupid fun deck... triggers pretty easily as well.  Step one... draw a bunch of cards.  Step two... get the combo in hand and drop Emperor Thaurissan.  Step three... Let the Knife Juggler do it's job.

Anyway, of the games I've played, I only didn't run into the combo once and got killed.  But every other time it's gone off and it's hilarious.  You are aiming to get the Grim Patron on the board, drop a Knife Juggler, hit that with the Deathspeaker, and kick off Defile.  There is a good amount of removal with this Tavern Brawl, especially with Sacrificial Pact.  A 0 cost life gaining targeted removal is always awesome, especially since everything is an amalgum.

I'm working on a Wild version, but for that to work consistently, I definitely think that Supreme Archaeology  needs to be in it.  Enjoy!~

Update****

I updated the list to be more of a nuisance. I swapped the Knife Jugglers for Ship's Cannon and the Twisting Nethers for Hungry Crabs. I also pulled Emperor Thaurissan and and Acolyte of Pain in favor of Galvanizers since it goes quicker. Give it a shot.
