Yes thats true, but depending on the battle, move set and stragety Heracross can be easily defeated. Plus Close Combat is Fighting type move and isn't very effective against a Fire/Fighting type pokemon such as Blaziken.
In order to truely see who can win between your Heracross Team and my Blaziken Team, you should do a two on two simulation like what you did on this thread.
My team consist of the following:
Blaziken @ Leftovers
Blaze @ Relaxed
Lv: 100
- Brave Bird
- Roost
- Agility
- Bulk Up
Rhyperior @ Life Orb
Lightningrod @ Lax
Lv: 100
- Hammer Arm
- Rock Wrecker
- Earthquake
- Rock Polish
