Torterra has great ATK & DEF in that order & decent HP but it's SP ATK is dead weight & it's Sp DEF is not good either. It's SPE is it's lowest stats meaning that it's meant to attack second so simply avoid using moves that prelong the fight & also have no benefit at the same time like Leaf Storm...it is it's signature move but does special damage so instead if you want a powerful Grass attack how about Move Tutoring Wood Hammer on the it. Other good moves for it are Chrunch, Synthesis, Earthquake, Curse & Leech Seed...maybe look through TM/HMs too.
Physical Attack/Speed Type
Staraptor has great ATK & SPE but not much of anything else. Though it does have decent HP & DEF for a Flying/Normal-type but equally terrible SP ATK & SP DEF, both of which have the same low rating so avoid battling Electric-types & even though it doesn't learn any special attacks anyway, it's best to avoid them period. This pokemon if trained right will be one of your secret weapons of sort against the Elite 4. Good moves for it are Brave Bird, Close Combat, Take Down, Aerial Ace, Endeavor, Agility & Whirlwind...for Staraptor at least 1 TM/HM move is recommended.
