252+ Atk Choice Band Tinted Lens Lokix First Impression vs. 252 HP / 0 Def Great Tusk: 162-192 (37.3 - 44.2%) -- guaranteed 3HKO
No Tera Bug needed to do an average of 40% to Great Tusk. Every time Lokix comes in, something is taking a very strong hit; even physically bulky Corv takes an average of 40% from Knock Off, so the few 4x bug resists still aren't completely safe.
If hazards aren't up, there's also U-Turn spam available versus slower teams, adding a bit of flexibility. Does about a third to that Great Tusk, so very significant chip.
