4th Gen SS team

Since my last thread like this has been moved and I have NO idea were, i will make a new one.

My team is this

Quilava
Lvl. 21
Flame wheel
Cut
Headbut
Ember

Zubat
Lvl. 19 or 20
Wing Attack
Super Sonic
Astonish
Bite

Machop
Lvl. 13
Low kick
Leer
Not sure what his third move is
Karate chop


So who else should I add to the team? I would like to get a Heracross but I can't find one yet.And besides him/it, who else should I add. I am not very good at judging what my team should buy or what types are good with what. Thanks in advance.

In-game team help threads belong in their respective section. (In-Game Team Help). As this team is incomplete I will have to close this. You're more than welcome to ask for help here, and I'd definitely recommend you take a look at In-Game Team Help's rules if (even if you don't!), do the beforementioned.
