I've been excited by the dynamics of control vs control matchups and how slower decks generate value. Was very nervous Jade made that null and void. But priests using Lyra and Shadowing more Elise Packs vs Ragnaros Hero Power is an interesting dynamic.
I'm becoming more excited by this expansion. I wish I had the time and money to play more decks though. It's brutal that so many great cards needed to run archetypes are epics.
Blizzard's smart though, they are making so much money right now.
