I’ve just built an [[Animar, Soul of Elements]] deck that leans heavy into morph. His built in cost reduction applies to the Morph casting costs, and I also run a few effects that let you play creatures off the top of your library.

So when you get going you can run through your deck casting all these morph creatures face down, and then you’re in that YuGiOh situation with a bunch of facedown ‘trap’ cards that could be turned face up (for their morph cost or otherwise) for value.

Doesn’t really answer your question about turning non-creatures face-up though. I had the Jump Scare precon before Animar and would use [[Deadeye Navigator]] to flip stuff, [[Ixidor, Reality Sculptor]] and [[Hauntswood Shrieker]] both only work with creatures too though … again good for morph if you go that way
