Chesnaught

Chesnaught's great physical bulk allows it to shut down unprepared physical attackers such as Excadrill, Mega Lopunny, Bisharp, Tyranitar, and Terrakion. Its amazing ability Bulletproof grants it immunities to common attacks such as Shadow Ball, Gyro Ball, Focus Blast, and Sludge Bomb. Its good support movepool with Leech Seed and Spikes gives it means of supporting the team, but the biggest change to Chesnaught in ORAS has been the addition of Drain Punch. With it, Chesnaught is no longer reliant on Hammer Arm, which drops Chesnaught's Speed, and can sustain itself while also hitting the enemy for decent damage. However, it has a huge number of weaknesses that hinder its defensive prowess, especially to Flying, which is made more problematic with the prevalence of Talonflame and Mega Pinsir in the current metagame. Its poor Special Defense inhibits it even further, meaning it is weak to many common special attackers. It's also very slow, meaning it can't naturally outspeed opposing walls. It also suffers from four-moveslot syndrome, as it is limited by its move choices. Additionally, Chesnaught faces competition from Ferrothorn as a defensive Spiker, which boasts a better typing and defenses. Despite these drawbacks, Chesnaught still can be quite a threat under the correct circumstances.
