Which reminds me - Counters:
-EQ users with superior Speed (with/without Trick Room).
-STAB Psyshock users with great Sp.Atk.
-Dusknoir, Spiritomb, or Eviolite Dusclops with Pain Split (rips hard into your beefy HP) and a follow-up.
-Toxic and Ghost-Type-Curse users. Your HP is a precious asset.
-Marowak - Your Subs can be pierced hard by STAB, Thick Club Bonemerang (and it'll ignore Static).
-STAB Seed Bomb/Bullet Seed/Razor Leaf users.
-Ferrothorn - Loves Static because of its low Speed and Gyro Ball, plus STAB Grass.
-Landorus, Gliscor, Flygon, and Claydol are immune to both of your STAB Types, plus Motor Drive Emolga (when released). The 4 currently out have access to Ground STAB and Emolga could use Hidden Power for one of those types.
