New competitive player looking for help

[geetry]

Mega Garchomp is a monster attacker, but always has the crippling 4x weakness to ice. I would at least have one pokemon who can counter Garchomp's huge weakness.

I used to run a mega Garchomp, and it made me realize M-Garchomp can't handle everything like I thought it could.

This is, if you decide to run the mega Garchomp instead of the Charizard X.
