>>31136303I personally only used it in singles, but i guess your pic related might be ok. However Earthquake hurts. Celesteela maybe?
Support and healing is always good so you can pair it with what you want, i guess.
Also while Leftovers is the best, other items might be interesting. Rocky Helmet, or even Z-crystals for stat raises.
Plus, in the case you have something set up Toxic Spikes, you can go and breed Venom Drench on it, to devise a road for a complete domination from your sweeper.
And you HAVE to get a shiny one.
