[Gen 8] Shield Wedlocke

I'm Playing pokemon Shield as a 3 Heal Per Pair Set Mode Wedlocke, and am about to face the 2nd raihan fight, the one in the champion's cup. Wish me luck since Ive had 18 deaths and I don't remember is 5 mons. I know there's Duraludon, Torkoal, Goodra.
Worst point of the journey was vs piers. He killed 4 pokemon. Including my starter.

I am Now Grinding For Leon. Wish Me Luck Because I'll need it.
About that raihan fight though... I didn't know torkoal had solar beam and he crit ohkoed on my starmie.
