Gliscor

Without abilities or status moves, Gliscor’s utility in the main games didn’t translate well in GO, as a combination of low Attack and bad moves prevents it from having any offensive purpose. It can make for a decent gym defender, capable of slowing down Machamp and harassing them with its Flying-type moves, but it will fall like a fly [scorpion] to anything remotely chilly.

Best PvE Offensive Moveset

• Wing Attack + Aerial Ace is one of Gliscor's STAB options, while Sand Attack + Earthquake is the other.

• Fury Cutter also performs well, due to its quick energy generation.

• Sand Tomb and especially Night Slash are underwhelming.

Best PvE Defensive Moveset

• Wing Attack is far better defensively than Sand Attack and Fury Cutter.

• Aerial Ace and Night Slash are similar, but the former is stronger.

• Earthquake is too slow to pose any real threat.

Sand Attack benefits from STAB and is preferred over Fury Cutter. It is also preferred over Wing Attack, due to the latter's average parameters overall.

Night Slash is valuable for the speed, only requiring 35 Energy, as well as the Dark-type coverage and the 12.5% chance to buff Gliscor's Attack stat by 2 stages at each use. Aerial Ace benefits from STAB and is also cheap to use. Earthquake can deal huge damage with STAB, offers wide coverage when used with Aerial Ace; it is expensive, however. Sand Tomb deals pathetic damage, but its utility is to debuff the opponent's Defense stat and baiting shields.

With a max CP of 2692, Gliscor lacks sufficient stats to perform well in Master League. However, the key coverage mentioned above impressively makes it a viable option here too.
