Flygon @ Leftovers
Ability: Levitate
EVs: 96 HP / 252 Atk / 160 Spe
Jolly Nature
- Earthquake
- Roost
- U-turn
- Toxic
This might be the single best excadrill check objectively and without fault. This mon is able to stomach every single attack excadrills stupid claw hands can dish out and retaliate back with its higher speed and likely kill with its impressive stab earthquake;
252 Atk Flygon Earthquake vs. 252 HP / 0 Def Excadrill: 414-488 (97.6 - 115%) -- guaranteed OHKO after Stealth Rock
Indeed, bar crits, which every possible answer can theoretically succumb to, Flygon should be held up as a bastion of sustainability against the stupid mole. Roost allows Flygon to stay healthy should it directly take a Sand Force Iron Head or Mold Breaker Earthquake, and U-Turn and Toxic allows Flygon to threaten a large SWATH of the metagame with either momentum or crippling status.
Not to mention there are plenty of other viable options as well, Fire Blast allows Flygon to more directly threaten Ferrothorn and Skarmory with supereffective damage and Outrage is a move that hits things. If one wanted to be particularly attractive they could even run Hidden Power Ice and a Naive Nature, which allows Flygon to retain its incredible Excadrill annihilating niche and 2HKO Landot while doing nonzero damage to Gliscor.
