In order to defeat Marowak, you’ll need decent prediction skills and something fast with good special attack and preferably a Water, grass or Ice attack. Prediction is required for when you switch in your Pokémon (since no one would send Marowak in versus a Pokémon with the ability to 1KO it before they can do anything), since if it takes any damage, it’ll most likely be a KO or near to that. After that, you’ll probably need to predict what Pokémon will be switched in to replace Marowak, since few people would leave their Marowak to be fainted.
