I use "scrotom combo"-fail? on every team i have, its deadly...in the team preview 1st thing i check for is for ground types, if not let rotom spam that shit..(V-switch)..its a nice team, not gimmicky at all...cept maybe for Xatu...I would run gliscor over it anyday...heck u dont have to use the toxic heal version, run sand veil n get roost and stealth rock back...
Gliscor @leftovers
Nature: Jolly
EV: 252hp, 252speed, 4 def
Sand Veil
Earthquake
U-turn
Roost
Stealth Rock
What I've given u is a mon thats faster then xatu, keeping momemtum, lighten the load on wash, and gives u a reliable way of getting at least the most important hazard in. The best counter to volcarona and nite, who looks like u have problems with, is stealth rock.
If u find it to be too much to have 2 4X weakness to ice, switch it for landorus...this gliscor is great as the lead spot...
