Here's my Dragon Priest:
I took out Brann for Sylvanas. Brann + Operative is pretty insane but he doesn't do much else.
I like the -3 attack potion. It's hard to get value out of, but when it works it feels like a 1 mana Win The Game card
The Potion of Madness probably sucks but I'm trying it out. It matches up pretty good against Patches Warrior I'm hoping.
Acidic Swamp Ooze seems like a must
Entomb is a terrible card right now
