Pokémon Violet - Mighty Infernape 7-Star Crystal Raid Solo (Koraidon) 

Here's another easy 7 star raid battle, as long as you have a decent fighting type like Koraidon. Four Mud Slaps was enough to charge a tera, but it turned out to have Aura Sphere anyway. I ended up using a few Swords Dances as soon it debuffed me, then it was a pretty easy victory with +6 Attack.
