Murkrow don't get WoW or Trick... and lacks Leftovers.
Murkrow does get FeatherDance, which will do in a pinch and is good enough on 'Krow to warrant use. Also, the reason why Sableye needs lefties is because even with max investment in its defences, it is still quite frail. With Eviolite, Murkrow is not, so can afford to forego lefties.
Having said that, they play very differently. Murkrow is much more of an annoyer with FeatherDance, Mean Look, Perish Song, etc whereas Sableye functions better as a stop to weather sweepers, set up sweepers and not to mention spin blocking.
