Yeah, there's those three (though doesn't Togekiss prefer Serene Grace for Air Slash flinching?), though I'm more thinking about Pokemon who learn quite a few of the Slash moves (or at least should). Sandslash, Persian, Scyther family, Kabutops, Gligar family, Sneasel family, Skarmory, Sceptile, Drapion, Gallade, Serperior, Samurott, Leavanny, Escavalier, Axew family, Bisharp, Swords of Justice, Honedge family, Binacle family, Lurantis, Sirfetch'd, & Zacian.
And yes, I know the flavor behind Super Luck doesn't quite fit some of them, which I guess then means creating a cutting/slash version of Iron Fist/Strong Jaw wouldn't be a bad idea (and if it provides a smaller Power boost it could also then provide a +1 crit increase too).
