Why didn't Ash use Charizard at all in the Sinnoh League?

Question

Title says it all.

Answer 1

Because Ash chose not to. He chose his Pokemon according to what he saw could beat his opponent best. Charizard just wasn't one of them.

Comments

Your information is also somewhat inaccurate. He can call Charizard to battle for him anytime he wants. He used it in some Battle Frontier battles, which was after Charizard was released.

He didnt release him just sent it for training
even if he released it it was master Quest
