Pokemon: Rate my Charizard!!!!?

Question

Okay I am currently about to raise a Bellyzard (charizard with bellydrum) here is the move set i choose and item PLEASE LEAVE YOUR SUGGESTION ON MOVE SET AND ITEM.

BellyDrum (for max atk)
Flamethrower(good fire move with good PP)
Substitute (to not allow a hit in after sunny day)
Sunny Day (boost flamethrowers atk further)

Ok I switched up the moves

Belly Drum
Fire Punch
Aeriel Ace
Substitute

Answer 1

Your Belly Drum is wasted since FLamethrower is a Special Attack, and Belly Drum only raises it's Attack stat

If your going for a Bellyzard set...

Belly Drum
Fire Punch
Earthquake
Substitute

Fire Punch now falls under the Attack Stat with the D/P Metagame

Answer 2

Belly Drum is useless if your Charizard doesn't know a physical attack so yehh replace Flamethrower with a physical attack like Aerial Ace and teach it shadow Claw instead of Sunny Day since Charizard gets a STAB from Aerial Ace

0/10 since Belly Drum is useless on your Charizard's current moveset

Answer 3

ill give it 5 out of 10 instead of sunny day try overheat and substitute change it to earthquake if u do that u will be unstoppable.
have fun

Answer 4

I would give it a 6 out of 10. only one attack does damage.give it more powerful attacks, like Fire Blast, or some fighting type moves

Answer 5

Trash sunnyday and go for a more powerful fire move, try overheat.
