>>52362906Blastoise has nothing to offer defensively that tens of other water Pokemon don't do better. Giving it a steel type will still leave it out class by all kinds of shit. The only way to give it a meaningful niche is offensively, but an offensive water type needs either a second stab or meaningful coverage against opposing water types to ever not be trash. If you're not gonna give it thunderbolt, turning it into a water/ground or even water/normal would help more than steel in this department
