Why are you not using fake out or psycho cut? Also, Medicham is faster and hits harder than Altaria, so I think you should put your important coverage moves on Medicham.

Could you recommend a moveset for each of these Pokemon including the same abilities, held items, and EVs? Because I honestly don't know what to do anymore. I'm probably just going to give this team up if I can't figure it out so will you help me?

What if I swapped Quagsire for Hippowdon? It would be like this...

Ice Punch
Thunder Punch
Brick Break
Psycho Cut
252 Atk 252 Spd 4 Hp

*Altaria @ Yache Berry
Ability: Natural Cure
Dragon Pulse
Moonblast
Ice Beam
Roost
252 Sp Atk 126 Sp Def 126 Def 4 Spd

*Hippowdon @ Rocky Helmet
Ability: Sand Stream
Earthquake
Fire Fang
Crunch
Yawn
252 Atk 124 Def 132 Sp Def

Sorry I messed up the previous comment. Fake out is good on Medicham in OU, not the Battle Tree. Just replace fire punch and recover with ice punch and psycho cut.

Ok thank you! I will do that :)
