In modern there is a deck that uses Eldritch Evolution and Allosaurus Rider to get early Griselbrands. There is a lot of card disadvantage there. In vntage we have Skyshroud Cutter. This does not get Griselbrand, but there are still good options for a win con.
This is the best card to get agaist most blue lists and may work against some Forge Shops lists.
I like this guy against Dredge. Fetching a Glacial Chasm and Strip mine, before setting up a Dark Depth win is good.
I just wanted to let people know this is out here and encourage people to mess around with it. this is on par with flash hulk, and we have preordain now. I also think serum powder is worth trying.
