Highlander Galakrond Rogue

Pharaoh Cat is autokeep in mulligan, and you should also keep Necrium Apothecary if possible, as it can start snowballing the game quite fast. Other than those, cheap minions and Backstab aren't bad cards to keep.

Please note that you only have three Galakrond Invokers in the whole deck so you can't be too greedy with when to play Galakrond.
