Abuse the capability of your deathrattles by reviving dead minions and summoning copies of them, as well as using some cheap spells like Psionic Probe and The Coin that you get from Gilded Gargoyle (as well as the shaman spells you get from Witch's Cauldron) to charge up your weapon and your spellstones.
