Is a shiny Whismur at a Rash nature with better-average ability and outstanding HP expectional to my team. Or instead a Hardy nature Bagon with flawless Attack, Sp.atk, Sp.def, outstanding speed.
Bagon will be tough to level up, but it's worth it when it evolves.Pick Bagon. Salamence is pretty tough, and a shiny Whismir is rare, but it's really up to you.
