I dont know much about pokemon cards and dont have this game, but since you have four charizards it must be very hard to beat.

With 4 Charmander, 4 Charmeleon and 4 Charizard, I almost always get a Charizard set up in less than 7 turns, with the help of all the Bills, Proffessor Oaks and Computer Searches.

Charizard is a powerful Pokemon, although I don't like it much, overall it is powerful.

Charizard is the best fire type pokemon.

Charizard can just swords dance up and make his attack more than 500 in just one turn.Arcanine cant do much, just flamethrower and a few physical attacks.

I'll give Charizard these moves:

Flamethrower
Earthquake
Rockslide
Swords Dance

This is what I'd give him too.And in R/B/Y, he can sweep a whole team of arcanines.
Charizard wont beat articuno in R/B/Y as he dies to one blizzard, as its super effective unlike in G/S/C.

Blizzard is supereffective against Charizard in RBY, but I don't think he dies in 1 Blizzard...

I think he dies, my charizard died to an articuno's blizzard on pokemon stadium.remember blizzard's power : 120.And articuno's got 348 special...

Maybe there's just a chance that it'll die. If it doesnt, it'll then 2HKO Articuno with Rockslide.

I'll be back in 20 minutes.

Charizard is much more powerful in G/S/C.His fire blast is very powerful, I think it did damage about as big as mewtwo's psychic to a blissey.

Mewtwo, despite having the highest Special attack in the game, he's Psychic is outpowered by most Pokemon's VHPSAs.

This is because psychic's power is not as high as these moves' power.And it might be weaker, but only fire blast is good on G/S/C and R/B/Y, and blizzard also but only in R/B/Y.
