I hope this was a WOTC leak. IT's not, we know that the foil sheet is probably out there in the wild, and we know that many big vendors are probably keen to get their hands on it(if they dont have a more detailed list already). So if we see certain buyouts or price spikes before the set is going to be properly released, we'll know wether or not it was a publicty stunt by WOTC.
One of the wrost graveyard hate for a while. Unless Legacy depth running 4 enlightened tutors breaks the white card, I don't see it getting play either.
Aggressive and big creatures don't work well together. Since big creatures takes time to play, so you're going to spend most of your early game not being on the offensive but on the defensive. If you want big creatures check out 12 post http://www.mtgsalvation.com/forums/the-game/legacy-type-1-5/developing-legacy/181890-primer-12-post.
There's a decent monogreen version of it. If you really want to splash red you can throw in pyroclasms or a punishing fire package.
Horse stompy is a go in Legacy
Half the decks in legacy wants 4 chalices in the board and being ~70$ each is dumb.
Impulse is probably your best bet. Other than that, Opt
Rip in pieces
Everyone would play it in Modern.
