Although they share a fairy weakness, Kyu-B is a fantastic partner for utility Sableye that both appreciates Sableye's support and supports it back. Common things that are used to overwhelm Mega Sableye include Tail Glow Manaphy, Magma Storm Heatran, Landorus-I, Earth Plate Lando-t, Serperior, Offensive Starmie, SD Gliscor, Thunderus-I and Torn-T. Kyu-B checks/counters every single mon on that list, and is able to come in on them repeatedly thanks to Sableye keeping rocks off the field with magic bounce, and we all know how dangerous Kyu-B can be with a free switch in and rocks off the field.
In return, Sableye Hard counters Chansey, AV Conkeldurr and Ferrothorn, three of Kyu-B's best checks. It also checks [Mega] Scizor and mega metagross, two dangerous mons that can switch in on Kyu-B with ease. It also helps Kyu-B by weakening clefable by knocking off its leftovers, bringing it into range of being 2hko's by Kyu-B's ice beam. Sableye also hard counters nearly every fighting type in the meta, allowing Conk to switch out easier.
To top it off, Sableye can easily keep hazards off the field thanks to magic bounce, allowing Kyu-B to come in freely without having large chunks of its health chopped away.
So these two mons partner very well together despite the stacked fairys and mega lopunny weaknesses they bring, the combination is nearly too good not to run on Mega Sableye balance builds.
