So, the other day, I was wondering if it was possible to make a Pokémon impossible to hit. The best I’ve got Is a Sheninja With the electric Tera Type, and an air balloon. But it can still get hit by Pokémon with mold breaker, or reshiram if it knows a ground move. Is there any way to make a Pokémon immune to Every single move?
Good as gold is the only thing in the game that blocks curse. Magic bounce doesn't bounce it, and magic guard only prevents its damage (so if a magic guard Pokemon is cursed and has its ability removed, it'll still take damage). source If a Pokemon has good as gold, it can't have wonder guard, which is the only ability that can completely block multiple types of attacks. source Conclusion: no.
