Hi guys today i was doing some pvp battles and i was using my stall team. In a battle vs another trainer i was with my clefable vs his muk-alola. I have done PROTECT and muk has done POISON JAB....with the protect i have took no damages but i have been poisoned from POISON TOUCH. That's a normal mechanic? Unfortunately i dont have a screen and i was not recording. Can u give me plz some explication about that mechanic? It is a bug or is the right way? Thanks.
