I'd catch a Shin because Shinx is the most awesome Pokémon ever and I love Shinx and it would be cool to have a Shinx and I should probably stop saying Shinx....
Oh and Shinx is my favourite Pokémon.
And by the way there aren't 1,000,000,000,000,000 Mews for all of you and they have a low catch rate so stop saying Mew, Mew, Mew, Shiny Mew, Mew, Mew, etc.
Seriously half of this freakin' thread says Mew
