So I was derping around with Techdex search
and I notice Fissure, Guillotine, Horn Drill, and Sheer Cold are on there twice: once with base power "KO", and once with base power "OHKO".
Edit: Stuff like Icicle Spear is also on there twice, once with 10 BP and once with 25 BP, although that's for cross-generational stuff.
Edit2: Wait, I posted this in the wrong section. DANGIT!!
