Sonny 2 Is not the best game ever. It is good, but there are many better games. Also after playing Sonny, I don't feel like doing the exact same thing over again with a few extra items to choose from. That just my opinion.
Sonny 2 is good but like the first one never had a definitive end. Although I keep saying they did well to give a new twist with new weapons and abilities to transform to Sonny. n.n
To answer the original questions, CD is cooldown, and Wraith form has a 10-turn cooldown so that is why you can't use it. Either that, or you forgot to put it in your bar.
