Alright, so I guess I need recommendations of sorts, or votes, as I need to select one of the three Pokémon to use on my team to counter flying types…this is in game by the way. Reasons are also appreciated.

Aron

Lileep

Cosplay Pikachu

Which do you choose?

The rest of the team at this point is Camerupt, Hariyama, Gardevoir, and Marshstomp.
