With its plethora of utility options and excellent defensive typing that makes it difficult to wear down via residual damage, Excadrill can function as an effective support Pokemon on a wide variety of team compositions, from providing a sturdy entry hazard removal option to checking attackers such as SubToxic Aegislash, Magnezone, and Mega Latias. Iron Head provides Excadrill crucial coverage against Ground-immune Pokemon such as Mega Aerodactyl and Enamorus and 2HKOes Clefable, allowing Excadrill to better deal with it. Toxic allows Excadrill to cripple a multitude of bulky Pokemon that would otherwise check it, from Slowbro and Hydrapple to Swampert and Hippowdon, notably allowing Excadrill to keep Stealth Rock off the field against the last two more reliably. Additionally, Excadrill can also use Stealth Rock to further support its teammates, most notably being a hazard setter that can consistently threaten Rotom-Wash, one of the most common hazard removal options in the tier. It's worth noting on teams that necessitate the ability to set Stealth Rock, Toxic can be used over Iron Head to ensure Excadrill retains its ability to threaten several of the aforementioned defensive Pokemon. Lastly, Swords Dance is an option that helps Excadrill break past defensive Pokemon such as Amoonguss and Slowking, enabling it to sweep teams late-game in conjunction with Rapid Spin's Speed boost. The first EV spread allows Excadrill to survive a Close Combat from Jolly Zeraora, outspeed Aegislash and Magnezone that run a Speed-boosting nature, and OHKO Choice Scarf Rotom-Wash and 2HKO most variants of defensive Scizor after Stealth Rock with Earthquake, with the rest put into Special Defense to maximize its ability to take hits from special attackers such as Mega Venusaur. On sets using Swords Dance, Excadrill should instead run maximum Attack and Speed investment with a Jolly nature to be as offensively threatening as possible. Pokemon that benefit the most from Excadrill's utility options include offensive threats such as Mega Aerodactyl, Mega Gardevoir, and Iron Boulder, which appreciate not being worn down by entry hazards as well as Excadrill's ability to cripple or take advantage of certain defensive Pokemon such as Clefable, Slowking, and Scizor for them. In return, these teammates can assist Excadrill in overwhelming Celesteela and Skarmory that otherwise completely blank it and help manage faster attackers such as Alakazam and Iron Moth. Similarly, other defensive Pokemon such as Buzzwole, Hydrapple, and Mega Latias benefit from Excadrill's hazard removal and ability to assist against threats such as Aegislash; lessening the first two’s reliance on Heavy-Duty Boots to manage hazards is also a major boon. In return, these Pokemon can help deal with Fighting- and Ground-types such as Mienshao, and Gastrodon and absorb Knock Off from Mega Venusaur and Zeraora that would otherwise cut into Excadrill's survivability. Lastly, certain Pokemon such as Swampert, Clefable, and Celesteela deserve a special mention; their role compression can help free Excadrill from the need to run Stealth Rock or check Pokemon such as Clefable with Iron Head, allowing it to be much more flexible in its moveslots and role compression.
