One of my Favorites. Teach it:
Recover: The original reliable recovery move learned by the original reliable recoverer.
Surf: STAB, good power, high accuracy, HM, type coverage, mainly deals with Fire types who you see a lot of.
Ice Beam: Good power, chance to freeze, high accuracy, used to deal with Grass weakness. Deals with Flying and Dragon types, two of the most commoly used types.
Last move is your choice. Here are some options:
Rapid Spin: I would choose this for competetive play to deal with entry hazards.
Thunderbolt: Good power, high accuracy, chance to paralyze, deals with other Water types and also the common Flying type.
Psychic: Only here for STAB. Horrible type coverage.
