No one really cared about this Pokemon when it was announced. I wouldn't even blame you if you forgot about it entirely. If you stumble upon it on the beaches of Alola, however, I highly recommend giving this hidden gem a spin.
With a Ghost and Ground typing, Palossand is set up with a total of three immunities: Normal, Fighting and Electric. It has a moderately high Sp. Attack and access to powerful Special Moves like Shadow Ball, Giga Drain, Earth Power and even Psychic.
Do you have a grudge against Aegislash? Then Palossand is your pal. Its high Defense stat helps it withstand anything Aegislash can throw at it and the typing advantage lets it steamroll right over the possessed Steel and Ghost sword. The only real issue is it's abysmal speed stat, like most of the Pokemon in Sun and Moon.
