I'm missing the achievements for getting 6000 and 6500 points, and I'd like to go after them, but the problem is, I don't know any decently reliable way of getting that. Does anyone have any ideas? Even 6000 is an extremely high score, so imagine 6500... I've heard it's much easier in doubles, so if you have anything for that, I'm not going to be picky. The only guy I've seen that actually gives out a team during a quick Google search said Garchomp, Noivern, Talonflame and Greninja, but no specifics other than that.
And no, Durant doesn't work here, because the longer the fight drags on, the less points you get.
