Seems strictly better than Cursecatcher in vintage, and I've seen it played before. RTR seems really sick for standard and modern, not too much for other formats besides Izzet Charm
It's not strictly better due to Merfolk being a deck, but having natural evasion and now card redundancy may create new variations of Fish, perhaps incorporating Ninja of the Deep Hours again.
Strictly is not appropriate. But in non tribal hate decks being flying with 8 x Exalted is pretty boss. It's also a relevant WHITE one drop in G/W hate bears whereas previously the only other one drop was Noble hierarch (student of warfare / mikeus aren't hate pieces just dudes).
Edit: Also ... INB4ORLYALTER
