Malleable Impostor
Clone effects live and die by their timing window, and the flash clause here rewrites the whole exchange. Most creature copies (the Clone lineage, the many creatures that enter as a copy of something you choose) resolve on your own turn, at sorcery speed, copying whatever is already on the board. Flash lets this one wait: hold priority through an opponent's combat, let them commit their best threat, then arrive as a mirror of it at instant speed, with flying stapled on regardless of what it copied. The restriction that pays for that flexibility is baked into the copy clause: it can only copy a creature an opponent controls, so it is a reactive tool, not a way to double your own bomb. The added Faerie Shapeshifter typing and evergreen flying are the tell that this was built for a tribal shell, where the copy needs to count as a Faerie even while wearing someone else's face, and where a flying body matters more than the raw stats it inherits. The printed 0/0 is irrelevant in practice; it never enters as a 0/0 unless there is nothing worth copying, in which case it dies immediately. What emerges is a copy spell that inverts the usual copy math: instead of duplicating your own strongest permanent proactively, it steals the shape of whatever the opponent has just exposed, at the moment they can least afford to see it turned back on them.
