Nah, uw landstill was my first true legacy deck. I did play counterslivers for a short period when I didn't have goyfs (damnit should have gotten em @ 5 dollars). I'm not claiming automation makes slivers amazing or anything, but it at least solves sliver's "not enough lords" problem. Who knows, it might end up being pretty good in the right meta. Having stp and shroud seems like a beating against other midrange decks like junk. Being flying also makes it truly universal evasion.
