Could I Beat the Elite Four(Pokemon Emerald)?

you don't have to use wailord now that you've reached the elite four. i would use sharpedo, because of it's ability, insane speed, and the fact that it is dark. another thing, double kick, really? there isn't a better move for blaziken??? that has to change. just level it up to 59 for sky upper cut or tm 31 birck break, and get rid of cut for something like bulk up to raise your other moves power the moveset for aggaron is fine. it would make sense to get rid of rock smash. aggron's weaknesses are ground, fighting and water. thunderbolt takes care of water, aerial ace takes care of fighting, and i guess you dont have anything for ground, but there is no point to rock smash so change that. you keep iron tail for the stab effect. you probably could beat the elite four if you plan ahead with revives and battle items, but not with those movesets alone, they r pretty bad. why have psybeam AND psychic? teach it shadow ball to fight alakazams weakness of ghost. solrock shouldn't know psywave because you can't trust it. find psychic if you can, otherwise just turn it into calm mind and try to recover what you lose with overheat. flygon is spot on though
