Wishing for an SC?

[UncleYee]

I grant that a crone or a master lich could wish for Power, but how effective would the resulting unit be? Relative to say a Cyclops, who has better stats out of the box (100 pearls really being all I want to spend here) than the crone after one or even two (or three?) wishes for power. (100 for crone, + empower from S0, + 100 more per Power wish (each subsequent one being only half effective). That's an awful lot of pearls).

Maybe wishing for a unit is so wasteful that it's not worth considering unless you're just messing around. But that seraph is tempting. And I'm still keen on the gorgon.
