Rate and Improve Pokemon Platinum Team?

I like your picks but I would have a legendary in there somewhere and a fire type as well like Charizard or Blaziken. I like Gallade though, good pokemon. I would also get a metagross cause they are pretty strong.

Houndoom is mainly special attack so i recommend flamethrower, dark pulse, solarbeam, sunny day. I trained one.

I'm not really a big fan of Froslass. I would go with Glaceon which can learn the same moves except for destiny bond.

Gallade's good no changes there.

Same for Whiscash i've trained one with the same moves.

The only thing I would change about Salamence is the return. Probably teach it iron tail to handle rock types.

I also have a Tyranitar and it's moves are earthquake, stone edge, crunch and ice fang. Tyranitar has a much higher attack than special attack so physical moves are your best bet plus this move set helps take care of all it's weaknesses except water and fighting types which are already covered by Gallade and Salamence.

Those don't even exist kid.
