How to Get Suicune - Pokémon BDSP

By using the Johto State in Ramanas Park, Suicune can be encountered and caught exclusively in Pokemon Brilliant Diamond.

How to Catch and which is the best pokemon to use

When you're facing Suicune, it is recommended to use Absol. Its moveset should include thunder wave and false swipe.

It is a reliable way to reduce the enemy's HP as much as possible.

To improve catch rates, you have to access a status-inflicting move.

If you prefer bulky water types, Quagsire is another option with access to Yawn.

And can be found in the Grand Underground.

Best Balls to Use

The Ultra Ball is a great ball to use if your quick ball fails to catch the Pokémon on the first turn.

After about a dozen turns, you can use the Timer Ball to raise your chances of capturing.
