Help me make a better Wifi team

use a double dance terrakion [rock polish stone edge swords dance close combat 252 atk/252 spe] item: rock gem/jolly nature over aggron because aggron is too slow and has bad typing so it isnt good in ou play. terrakion also forms a good offensive punch with salamence and infernape, and they can work together to beat each others counters, since salamence is able to kill a lot of the pokemon that wall terrakion, with fire blast/draco meteor.

also because terrakion has trouble with gliscor i suggest hidden power ice on infernape [along with a naive nature so you dont lose power] and using salamence's 'Classic MixMence' set found on its smogon page

every trainer should battle in his/her own way, developing unique strategies ect.
maybe use the team you have set up and and have a test battle with another trainer so you can get a feel of how to use them in a real battle and the opposing trainer can give you a little feedback, telling you where you made a mistake or what you did that was good.
also ,(this is just what i do) but i have a normal team along with others i trained to switch in and out of my party ( to improve strategy )

your team looks pretty good in texts but thats all i can say outside of battle....
i did notice your Infernape is good in Sp.Atk and weak in DEF
The Fire/Fighting typing gives it four weaknesses: Flying, Ground, Psychic and Water
ur gonna want to be able to counter (at least) one of those w/ an effective move
