Really boring submission but tank Rhydon is a hard check to Archeops. Has a high chance to avoid the 3hko from Archeops' Earth Power and OHKO's in return with a 3 hit Rock Blast. Only reason I consider it a check instead of a counter is that it lacks recovery so it's susceptible to being whittled through repeated switch-ins.
16+ Atk Rhydon Rock Blast (3 hits) vs. 0 HP / 0 Def Archeops: 324-384 (111.3 - 131.9%) -- guaranteed OHKO
4 SpA Archeops Earth Power vs. 252 HP / 240 SpD Eviolite Rhydon: 122-144 (29.4 - 34.7%) -- 8.8% chance to 3HKO
