Sableye

Thanks to its extensive utility movepool alongside Prankster, Sableye is a decent defensive Pokemon and stallbreaker. Its good physical bulk when invested allows it to check prominent physical threats like Silvally-Ghost, Doublade, and Gallade. It's also a spinblocker that stops common spinners like Eldegoss and Sandslash. However, its low special bulk and its merely okay Defense that requires full investment leaves it at the mercy of many special attackers, like Charizard, Ribombee, and Whimsicott. Dark-types like Sneasel, Shiftry, and Thievul also prevent Prankster from working, allowing them to easily set up. Sableye cannot switch into strong wallbreakers like Lycanroc and Trevenant easily, lest it risks huge damage.
