You can only have three pokemon in the battle subway(for single,4 for double,two for multi) at one time so I would use dusknoir zapdos and volcanoro
for duskonoir give it left overs and get rid of pursuit for protect or painsplit
for zapdos get rid of agillity unless you really want it and tach it hyber beam or light screen depending on which you want
for volcanoro replace heat wave replace with flamethrower which can be fiound in the abundunt shrine
get rid of phycic for hurricane.
ability flame body
other pokemon...(in case you want to use them instead of the ones I chose.
on torterror get rid of withdraw for curse,solare beam for earthquake and leaf stom for stpone edge(can be found in challengers cave)for coverage.
give it earth gem
ability sheel amour(dream world)
no problem with audino but it is a rubbish pokemon in general I wouldnt ever use it but its heal pluse heals the other pokemon(opposing)so it could be ok for double battles.
get rid of simple beam for you turn to use regenerator
item sitrus berry
and spinda no way never use it its crap
help I hoped and sorry for the spelling mistakes(i bet there are loads!!)
