>>53893513>>53895070OU is doable, just because of how relevant Sun is. I'm not sure how likely that is to last with Heatran running around again, but "has Eruption in Sun" is a niche on its own worth using. It's basically doing what Gen 8 Charizard did, since Charizard doesn't have Weather Ball anymore, so it doesn't hit as hard as Typhlosion-Johto anymore. Hisui would've had stronger Eruptions regardless. Chi-Yu being banned also gives it a reason to ever exist, which would be stronger and more reliable than either.

- Eruption
- Shadow Ball

- Overheat
Run Blaze so when you get chipped you can at least click Overheat. Tera Fire eruptions can break past ridiculous shit, and STAB shadow ball with focus blast coverage is all you strictly need elsewise.
