More Legendaries to choose from.

Regice, Regirock, and Registeel. (Damn you Lazer.)

Articuno, Zapdos, and Moltres.

Mew and Mewtwo.

Celebi and Jirachi. (I just paired them up. I don't even know if this is a real pair from a game. But oh well, they're cute, they should be in games together, right?)
