Can the pokemon be from any region? or just sinnoh?
Any region, but not any hacked legendaries, try to make it as legit as possible.
Alright then, I'll think about it.
Flygon has all worse stats then Garchomp and can learn the same things. Garchomp can tear it to pieces, due to much higher attack and higher speed, before it can even get a shot off.
If you choose to use it though, instead of brick break (which it can't learn) maybe stone edge or rock slide to take out ice pokemon instead.
Sounds about right to me..
Although i have ran in2 few flygon(s) who were faster than my 1 of my palkia's, and flygon attack stat is also a beast. But6 garchomp is or porbably faster thn flygon.. Only 1 way to find out.. (ev'd train Flygon).... and sounds like a battle to me..
Spiritomb
Sucker Punch (Or Dark Pulse for more PP)
Shadow Ball
Dream Eater
Hypnosis
I like that combination, definetely Dark Pulse instead of Sucker Punch, since Spiritomb has better Special Attack then Attack. Overall that is a really good combination.
