Shadow Charmander

Charmander is one of the three Pokemon that players can choose from at the start of Pokemon Go, and will be the best choice for raids and gym offense of the three. If you want to evolve it into Shadow Charizard until we have another event that allows it to learn the exclusive move Blast Burn, it's a great Fire-type attacker. It will also be pretty good in PVP given Blast Burn, so that's worth considering as well. But for now, it's probably best to just save that dust and keep searching for a stronger Charmander.
