My take on the mill rogue. I tried to make some use of the Untamed Beastmaster and create something less expected. You can get some beasts buffed while milling. Dire Mole with 5/7 stats is fun:)

I did not manage to climb past rank 7 with this deck. Mech variant is probably more reliable. I do not have Valeera the Hollow, which is in my opinion auto-include in mill deck.
