EVs: 252 S.Defense, 140 Defense, 118 S.Attack
If you are wondering what the image above is it is a Clione which is the real life sea creature Phione and Manaphy are based on. Acid-armour is for boosting defense. Aqua-ring is for healing, but if you are on a rain team and already have Rest you can use Toxic. Scald is STAB and can burn. Rest is for if you are on a rain team, otherwise go with Ice-beam for coverage.
