I got an evil snowman treasure card and I got three pips to cast it but it was still grey! I also had a ghoul treasure card that did the same thing! What happened to them? :(
I think i migt know what the problem was. If one or all of the pips was a power pip and the card is not from your school it will not be availble to cast. I ran into the sam problem and thought i was doing something wrong till i waited and found that if all pips are white it would cast and if there was a power pip that i had to wait an extra round or untill i used the power pip with a card from my school. Hope this answers your question.

Are you sure you applied them to the right card? they have to used ON the snowman card THEN casted.
