Gender transformations are always nice, I have gotten a reputation recently with transmute flesh to stone which well... maybe bad end anon would really like that one. Furry transformations can be fun but not really something I have used on hapless victims... Although that gives me some ideas. Recently I have joked about "transmute flesh to robot" and vice versa as well as a polymorph plush spell. err... well it would really just be turning someone into an inanimate object you just chose to make it a plushie. hope that satisfies your imagination.
