I dunno, it can do some really strong things, but it's mostly gonna be fairly pricey to do them. Virulent Sliver is probably the strongest thing you can do with it since that's so cheap to cast, but other than that I'm leaning towards thinking it's not much or at all better than [[Reflections of Littjara]]. Reflections costs more but after that the copies come down for free.

And Lazotep Sliver is looking really strong, so not all the other ones are mid.
