You still have to pay to flip morph / manifest cards face-up, though.
Eldrazi ( at least the legendaries ) generally have some form of protection, too: Ulamog is Indestructible, Emrakul has protection from colored spells, and Kozilek ... well, he wouldn't fare so well. Current standard really doesn't have a lot of spot removal, though. Or, well - not cheap removal. Utter End would take care of even Ulamog ( or gods, or ... just about anything ), but it does cost 2BW. Murderous Cut is 4B, but has Delve, so that works. And, of course, there's Hero's Downfall - but that'll go in six months, so ... yeah. Who knows what next year will look like?
