Maybe you got that response because you initially seemed to suggest suiciding the trolls so you don't have to pay upkeep for them and basically using the spell entirely to get more gems via the kings.

I also find it hard to see how going for kings to get more gems makes sense. You'd have to be playing a huuuuge game for 45/55 turns to be a sensible amount of time to wait. If you have the time and resources to set something like that up my feeling is that you could have done a thousand other more effective things to help you win instead.
