I think you have to fight a trainer with bonsly and keep using the VS seeker until you see a sudowudo
OR you can get pkmn Colosseum, a TV, a Gamecube, a GBA link cable, a GBA, another Nintendo DS, and a Pokemon Dimond and Perl , snag a swodowodo in Colosseum and purify it, trade swodowodo to a GBA Pokemon game, see all Pokemon in diamond and Perl, import swodowodo to Perl or Daimond, and then trade it to Platnum.
its not worth it unless you have all those things in the first place
No trainer that you would battle in Pokemon Platinum has a Suicune. The trainers you face in the game use Pokemon that can strictly be obtained through normal gameplay, and do not possess any legendary Pokemon.

The only Pokemon Trainer i know that has a Salamence is Riley, you can find him at Iron Island. But, you can only battle him at the Survival Area in the building next to the Pokemon Center.
In Pokemon diamond, Pearl and Platinum you can see the evolved form of Finneon, Lumineon, on Route 223 in a trainer battle. The trainer who has a Lumineon is called Miranda. In Pokemon Platinum the trainer Cassandra also has a Lumineon.

On route 218 when you battle a trainer. the man with blonde hair who is a guitarist
this question is worded weird but if your question is "where do you get all thePokemon in Pokemon platinum?" then the answer is to battle every trainer in Sinnoh.
