So I have been attempting to get the trophy from the Super Doubles train in B/W2. Currently I have been using a gimmicky "skill swap" team of Regigigas (with toxic orb) and a scarf'd timid sigilyph. It works well enough especially paired up with my helping hand cressalia but around round 20 the team becomes unreliable. Does anyone have any tips or team suggestions for reaching that battle 49?
