This is actually a really cool combo, and it makes me hope Leon's Charizard has its Hidden Ability.With Solar Power, Charizard is more powerful than Mega-Charizard Y (475.5 vs 417 or 552 vs 485 depending on Nature) and can hold items, which, as we all know, helped get Mega-Rayquaza banned from Ubers. Oh, and even though Dynamaxxed Charizard doesn't have Drought, he does have more powerful moves that can break through Protect with secondary effects, like oh I don't know... Max Flare's Sun.
