Suicune - Return in case of another water monster.
Houndoom - I'm obsessed w/ Return but it comes in very handy.
Mewtwo - Psychic, Recover, Shadow Ball (most would dissagree but it is very good on certain Mewtwos. Mine has high P. Attack too.) And go with Thunderbolt for some thunder power since no one else has it.
Baby I like it.
