Buff the spells, most commonly through early Felfire Conjurer + Drakkari Enchanter. The rest of your board are cards that can take advantage of the buffed spells. Fauna Whisperer benefits a lot from the end of turn/spell buff synergy, and ideally you put it next to an Nightmare Par-tea Guest to buff your entire board. Famished Felbat can eat the shop after you've buffed it using Fauna Whisperer, as long as you position it last.
