Handlock updated for Ashes of Outland. While Mountain Giant is gone, other new Cards like Imprisoned Scrap Imp , The Dark Portal and especially Shadow Council can provide massive value if the Hand is big enough. Cards like Valdris Felgorge, Abyssal Summoner and Zzeraku the Warped from Descent of Dragons have already proven to be strong and support the new cards very well. The other cards are mostly survival tools like Maiev Shadowsong and Khartut Defender. Sense Demons could replace these cards if the meta allows it. With the new rotation, Arch-Villain Rafaam might become a lot stronger due to a lot of horrible Legendaries rotating out, but the deck doesn’t really need replacements in the late game, so I cut him (for now).
EDIT #1: Replaced Magtheridon with Riftcleaver. I forgot about the Anti-Synergy with Kanrethad Ebonlocke. Thought he would come back as 12/12 if he was awaken back in the game already.
