I would definitely agree with Godsu*. You want Yamato on teams that capitalize off of quick offensive damage and pressuring combos. The issue there is that if you aren't on par or stronger than your opponent you risk him getting killed very fast as he isn't tanky at all.
Alternatively, Jirobo can still do a decent amount of damage and with a proper lineup, such as the Kabuto Jugo curse team or alongside Kabuto Kimimaro for super tankage, you can become nearly unkillable with the stacking passives and still do quite a bit of unexpected damage due to their high modifiers.
