This is either better or worse than a half a Storm the Festival every turn depending on how you build your deck, and thats decent territory
Numerous writers, artists, and developers collaborate to create and release a new set of cards every quarter
Id sacrifice Composite Golem, bring it back with Nim Deathmantle and dump all that mana into a storm of spells (to go wide), or a single card like Walking Ballista/Golem Artisan to close out the game
Depart the Realm This is definitely a playable card in my opinion, and there's a weird playable loop for it, and you can just get it out of your hand and then use it when you need it
You spent four Black mana and drew 7 cards for 7 life
Scurry of Squirrels is also an easy way to activate Beastmaster Ascension or pump up Sword of the Squeak and Honored Dreyleader
