>>47378971Black got better with Gen 8. Icicle Spear is somewhat unreliable, but it's potentially 125 base power. Not to mention it got Dragon Dance. With Fusion Bolt and Icicle Spear, it has boltbeam coverage, letting it hit 99% of Pokemon for at least neutral. Kyurem-W still gets completely mogged by Heatran, Blissey, and Kyogre if not running Freeze Dry.
All Kyurem-B needs now is Glacial Lance and it'll be perfect.
