Ghoul Lord's little brother. It takes 3 energy to play (1 black and 2 normal). It's a fairly good unit at 3HP/3AP, and has the ability of eating dead allies in the Graveyard in order to restore 2HP. Like Ghoul Lord, you can feed it corpses with Sacrificial Altar to prolong its life. With the Ghoul Lord, it can hold its own against a wide range of things, but doesn't have many special abilities or uses save for that.
Strong against: Just about any weak ally without any good tricks.
Weak against: graveyard-emptying decks (Like Ghoul Lord, Savage Ghoul can't heal if the graveyard is empty) and filler decks with many cards in play at once.
