For Challenge # 134. Not a new morph mechanic per se... I just think Manifest was a little too specific. In a set that's full of morphers, this is a great card. Put it in a normal deck, and it's two bears for four - still good. What's keeping the spell in check, however, is that you need to put two cards in your graveyard first. For a set like Tarkir, this should have been relatively simple.

That makes sense, albeit I seem to recall the reason for not doing it is they didn't want to mix manifest cards your opponent knows what they are with ones they don't.

It's smart of them, but simultaneously short sighted. Going forward, every time we turn a permanent upside down, there's going to be the 'doesn't play well with Manifest' problem. Maybe it won't matter in sets that don't include Manifest. But any set that does include Manifest can't include a simple blue instant that turns an artifact into a face down creature.

I guess you win some, you lose some. I just wish Manifest came with a counter or something.

Well, they almost never did that before either, presumably because it could be confused with morph. I assumed that they'd be happy to have something else instead of manifest in a future set, as long as there weren't both at once, but I'm not sure shrug

I thought the reason they didn't print manifest from hand or graveyard was to prevent it from just being Show and Tell or Animate Dead.

Yeah, dude1818's take on it matches what I recall.
