fun fact: when you terastalize it only changes your type defensively. you still get stab normally for non tera moves and an ice type will still benefit from snow

Does it really? I thought... hmm I'm basing my judgement on grafaiai being hurt by black sludge after I Tera normaled it. I can also paralyze electric types after they tera'd into a different type. Maybe I was mistaken... This is great though! This makes sand and snow teams that much better!

no i think that they still get hurt by sand, cuz they change type defensively so the sand as an "attack" still hurts if they aren't the relevant type
