What do you suggest
i suggest a water or fire type at least
i think you should get rid of chesnaught- i honestly don't think it's great
keep nidoking, and choose between clefable and sylveon to remove
get rid of mewtwo too
you can keep the pidgeot if you want.if you like grass/fighting types, i suggest breloom
it's really up to you what pokemon you want for a mega- but i don't think you should use mewtwo x. that's the only one i don't think you should use.
