I really want WotC to make this token! This card is pretty hilarious, mainly because it involves an elephant. There are tons of decks that can use this card: Dredge decks, Karador, Ghost Chieftain decks, Jarad, Golgari Lich Lord decks, Splinterfright decks, and Morality Shift decks, just to name a few. Even outside those decks, this can be really useful if you're losing in the late game. Now, there are two main problems with this card. First, it gives everyone an elephant, which means that if someone has more creatures in their graveyard it'll be bigger than yours (still, a Phelddagrif EDH could use it). Secondly, and more importantly, it's only sorcery speed. Unlike Svogthos, the Restless Tomb, you can't make a super-Ted to block a Jokulmorder. Still, a decent card.
Pros: Makes an elephant Svogthos
Cons: Gives everyone an elephant Svogthos, sorcery speed
