Seeing as there's no physical/special split in 3rd Gen, try this:
Thunderbolt
Ice Beam
Earthquake/Rock Tomb/Double Edge/Iron Tail/Flamethrower
Brick Break
This gives you BoltBeam, + your preferences.Flamethrower gives you coverage over, uhh....Aggron,other steels (T-Bolt does more to Skarmory), and Ice-types, with more accuracy than Iron Tail-for the E4
Earthquake is brilliant, however Hoenn doesn't help it, with flying gym leaders, levitaters galore in E4, etc.
Double Edge is super-powerful Rock Head abuse.
Rock Tomb does good on Flyers-good for Drake, however you already have Ice Beam
Brick Break covers Dark,Normal.And is a screen-breaker obvs
