I didn't like the Slice n'Dice, i hate headcrack, for me it's the worst spell in the game and couldn't even see any possibilite to have another spell like that. I liked a lot of Tame Beast, maybe very situacional but works like that legendary that kills a beast, maybe a bit very op. But nice cards. Purge is just like anti silence? I liked the idea, good cards we don't have in hs something like that yet
Edit: Soulwell is nice, i would like to see something like: your hero power no longs damage you or your hero power now cures you, would be something different and maybe good for warlock.
