My life would suck without you
Darn it Mac, I was going to do Vulpix.
Challenge complete. Cloyster was never a bad Pokémon. In fact, it was OU in the first three generations. It then fell down to UU in D/P but it still was a decent Pokémon. The reason why I've chosen Cloyster for this challenge though is because of the major boost it got in B/W, Shell Smash. It turned Cloyster from what was once a Pokémon that was mainly used to set up and spin away Spikes into one of the most dangerous sweepers in the game. Cloyster is now back in OU with little chance of moving anytime soon.
