Gliscor

Respectable bulk, few weaknesses, resistances to Fighting and Bug, and key immunities to grounded entry hazards, status, and Ground- and Electric-type moves provide Gliscor with ample opportunities to come in and set up a Substitute or just threaten opponents with its STAB Earthquake from its very usable Attack stat. Poison Heal and Protect provide excellent passive recovery. As one of the premier Groudon counters in the game, Gliscor can also contribute excellently to a defensive core if necessary. Unfortunately, it is very weak on the special side, so in some scenarios Gliscor can turn out to be completely dead weight. However, if you play to Gliscor's strengths, it will prove to be a marvelous asset to your team.
