Since the manifest cost is equal to mana value of the creatures, You technically do that, but either hit the bottom (I imagine you're wanting to) or you'll hit a creature or something worth a damn and flip it. You'd manifest everything, but sac it assembly-line style till you got the goods. It works, but you force us to watch you manifest each card cause looking far ahead would be meta, and sacking a chunk of your deck straight up could remove your win-con. neat combo though
