My first team - review required

[Yasur]

Hey guys,
Recently I finished all the regions in this awesome game which is PokeMMO. I learned about IVs, EVs, breeding and more things, but I need your help with my team.
I don't know but I feel I'm missing something.

My team is:
Scizor - Adamant - Choice Band
Tyranitar - Adamant - Choice Band / Leftovers

Garchomp - Jolly - Leftovers
Rotom (Wash) - Bold - Leftovers
Cofargrigus - Bold - Leftovers

Conkeldurr - Adamant - Flame Orb

Personally I feel my Tyrnitar is kinda useless and I don't have any true wall in that team - are my thoughts right?
I count on your help so someday I may get higher on the ladder.
Thanks!
