Moveset:First Impression/Liquidation/Poison Jab/Leech Life
This moveset is really random.So a good strategy is to have 5 tanky Pokemon with high defenses, sword dance with them and tank a lot of hits, then baton pass to golisopod. With max attack,it will hurt the foe a lot.
Another strategy is to let the foe hurt your golisopod to half health, emergency exit, a tank come out, tank the attack, switch to golisopod again, first impression, emergency exit, a tank come out........
That will sweep through you enemy's team
