Oh, man! Cloyster is gonna be so broken in the 5th generation! Just a little joke to break the ice! Oh, man, I crack myself up.
In all seriousness, you can EV train in the fourth generation, but don't evolve it until you've given it a Heart Scale in BW so that it learns Shell Break/Crack/Smash/whatever it ends up being called when it comes out in English. Available as an egg or hatched and shiny.
Shiny version Fully redistributable as long as you use a pun when offering it.

Same as the other one, but modest. I probably should have gone with Shell Armor, but I forgot to change the nature in RNG Reporter. Available as an egg or hatched and shiny.
