In theory it might have a niche as a tank with Intimidate, T-Wave, and maybe Roar. Granbull is more powerful and has access to Heal Bell, but Stoutland is much faster and bulkier so it should have an easier time tanking. I don't think that's a very useful niche, but you can test it if you're desperate for a way to make Stoutland viable. I don't think it deserves an analysis though tbh.

yo honko, I heard from DC that you know of a niche for Stoutland.. can you tell me? :3 I can't find one that isn't outclassed by kanga or tauros

Congrats ^^
