I haven't played my Diamond version in a while so I loaded it up and it appears I was smack in the middle of breeding a bunch of Pokemon in order to start a new battle tower team. If memory recalls, I was gonna do a Sandstorm team. Can anyone point out if this team has any glaring weaknesses?
Tyranitar
Nature: Jolly
EVs: 4 hp / 252 atk / 252 speed
Stealth Rock, Crunch, Rock Slide, Fire Punch
Gliscor
Nature: Timid
EVs: 252 hp / 196 s.def / 60 speed
Baton Pass, Rock Polish, Swords Dance, Ariel Ace
Garchomp w/ Life Orb
Nature: Jolly
EVs: 4 hp / 252 atk / 252 speed
Dragon Claw, Earthquake, Stone Edge, Fire Fang
My idea is to have Tyranitar start things off because of his Sand Stream ability, and I gave him Stealth Rock since he's my opener. After he uses SR I'll just try to sweep with his insane attack power. Gliscor is obviously my baton passer, meant to set up Garchomp who should KO anyone once he gets passed a Rock Polish + Swords Dance. Even if Gliscor gets taken out, a Garchomp with Life Orb and sandstorm coverage should probably be able to take almost anyone out.
