Charizard have 4 ways to boost its physical attack (dragon dance,hone claws,sword dance and belly drum). Homever, it have a greater spatk and better special attacks Physical set Charizard@heavy boots -flare blitz -dual wingbeat -dragon dance/sword dance -earthquake Special set Charizard@choice specs -Flamethrower/fire blast -air slash/hurricane -focus blast -dragon pulse
Which one I choose?
Charizard is a lot better at special attacks. As well as having a higher special attack stat, hurricane is more powerful than its physical flying moves, and flare blitz's recoil makes it more difficult to sweep. This is the moveset I would recommend.
Charizard @ heavy-duty boots Ability: blaze EVs: 4 Def / 252 SpA / 252 Spe Timid nature - defog - flamethrower - hurricane - roost
Charizard needs roost and heavy-duty boots because choice specs still doesn't allow it to get enough OHKOs. It forces a lot of opponents to switch, which makes it one of the best defoggers in the format. source source
