Trick 10G 10

See "Trick 15" for tips on this. There are lots of reports out there of people triggering their Trick 15 achievement while their Trick 10 stayed locked, so this seems buggy. Sometimes it stacks, sometimes it doesn't. Try going for exactly 10 tricks, no more, no less if you're having trouble. I can't promise this will work or even that it's necessary. My 10 popped on a 14-trick combo, and my 15 popped on a 16-trick combo, so there's no being certain.
