Excadrill

Ground

Sand Rush alongside its phenomenal Attack stat allows Excadrill to become a potent revenge killer for Ground teams, taking on threats such as Zarude, Keldeo, Barraskewda, and Choice Scarf Tapu Bulu under sand. Excadrill's decent natural bulk allows it to live attacks such as unboosted Galarian Moltres's Fiery Wrath, Choice Specs Dragapult's Shadow Ball, and Hydreigon's Flamethrower. Excadrill's part-Steel typing allows it to take neutral damage from Ice- and Grass-type attacks such as Weavile's Ice Shard and Tapu Koko's Grass Knot and resist Dragon- and Psychic-type attacks such as Latias's Draco Meteor and Psychic. It also has Rapid Spin, which allows Excadrill to clear entry hazards off the field; this gives Ground teams their only and reliable form of entry hazard removal. However, Excadrill relies on sand to outpace most offensive threats such as Choice Specs Zapdos, Victini, Tapu Lele, Blacephalon, and Nidoking, leaving it easily revenge killed outside of sand.

Steel

Excadrill is an effective revenge killer and late-game cleaner for Steel teams, making it extremely valuable in the Electric, Poison, Psychic, and Fire matchups. Its ability, Mold Breaker, is extremely useful, as it allows Excadrill to spam Earthquake without being bothered by Levitate users like Rotom-W and Galarian Weezing. However, Excadrill is slower than most Choice Scarf users and gets forced out by those that carry super effective coverage such as Blacephalon, Tapu Lele, and Galarian Darmanitan. Furthermore, Excadrill struggles to deal with physical walls such as Slowbro and Galarian Corsola, which means that it needs support from teammates like Aegislash and Bisharp to break down certain defensive cores.
