Aggron

[CAMountainSnake]

I have decided to raise an Aggron for my final team. The Aggron I caught is a Shiny, and I want it for its uniqueness. However, it does not have the Rock Head ability, it is Sturdy. So I need a move other than Double-Edge to out on it. Any suggestions for the fourth move in a set of Iron Tail, Iron Defense, and Metal Sound?

Return
Earthquake (best bang for buck)
Rock Tomb (STAB plus speed drop makes this quite tatsty)

Why Metal Sound? Is this for 2v2? Metal Sound sharply lowers Special Defense and you have no Special type attacks listed. Roar would usually be a better choice there.

Also, what's its personality and DVs? If its +Special Attack you might
want to consider one of its Special Attack TMs to target other Steel
types (i.e. Fire Blast or Thunder). In *this* case retaining Metal Sound
make more sense.

What about Iron Tail, Iron Defense, Sandstorm, and Rock Tomb?

Those Moves have no real power and wouldn't do well when battling against other people. Maybe you should listen to rinku's suggestions because they sounded quite good when I read them.

Adamant Personality would be great, but since you have a shiny, you will have to work with whatever personality it has. EVs: 252 Attack, 129 Defense, 129 Special Defense
