By 'all-out attacker' I mean that I don't want it to have any status moves, and I want it to do as much damage as possible to most of the types. I've already sorted Dialga, it's moves are:
Ariel Ace - for Fighting, Bug, and Grass
Ice Beam - Dragon, Flying, Grass, and Ground
Earthquake - Electric, Poison, Fire, Steel, and Rock
Iron Tail - Fairy, Ice, and Rock
It does Super-Effective damage on 13 of the 18 Types (including its weaknesses: Fighting and Ground), with STAB and the Adamant Orb for Iron Tail, and does neutral damage on the other 5 types, so dual types shouldn't be much bother. I just need something like this for Palkia, and I'll probably need Dragon Claw, Aqua Tail, or Spacial Rend for the STAB/Lustrous Orb. I know this is very specific, but any help will be appreciated.
