I think Emerald could benefit from an extrovert. And Yama is a very 'roll with it' kind of guy, and he has the hidden SHANKASAURUS that Emerald has. I think he could be good combobreaker! In that he isn't 'in pattern' but would contribute and add to the team instead of weigh it down. Also Emerald has a lot of tsun and we know Yama is great with tsun.

Do you have any other ~app ideas~ even if they aren't app plans?
