Why is Bisharp not on the list? It's selling point are a strong Sucker Punch and unique typing, but neither of these things are enough of a reason to me. Absol has more power behind its Suckerpunch, and offers more versatility overall. Bisharp may have more physical Defense, but that's pretty much a moot point when you consider the prevalence of Mach Punch and Earthquake, not to mention the plethora of Fire-type moves available (and used for Forretress and Ferrothorn) that can easily take down Bisharp (many of which are Special-based anyways.) I'm not arguing for Absol's addition to OU; I'm arguing for Bisharp's removal from the tier. A unique typing isn't enough to automatically merit a spot in the OU environment. Bisharp is too slow, frail, and vulnerable to common attacks.
