I haven seen Mamoswine or Tyranitar in a while. What happened to them?
It’s hard to believe how two of the strongest hitters in OU have drastically fallen in popularity, only because of the recently created beast of CAP: Colossoil. Colossoil’s high base 122 Attack stat and great base 95 Speed; fantastic offensive typing in Dark/Ground; ability, Guts, to further enhance its offensive potential; and gargantuan movepool, which includes Selfdestruct all contribute to the overlooking of Mamoswine and Tyranitar. Colossoil is arguably better than Tyranitar at Pursuiting Ghost-types, such as Rotom-A, as it doesn’t care about Will-O-Wisp due to Guts, resists Shadow Ball, and is immune to Thunderbolt, which greatly affected Tyranitar who was once known as the best Pursuiter. Access to Sucker Punch has also made Colossoil that much better at Pursuiting enemies, as it can force a mind game against the likes of Latias and Gengar.
