Manor of Murky Vision

Manor of Murky Vision has phasing unless
you control a Merfolk Wizard. (It phases in
or out before its controller untaps during each of their untap steps. While it's phased out, it's treated as though it doesn't exist.)
Whenever Manor of Murky Vision phases
in or out, create a blue 1/1 Merfolk Wizard creature token, then add {u}.
