It's kind of hard for me to see what you mean because the silver haired prettyboy swordsman that's gifted yet tragic that everyone loves isn't really something I'd consider a cliche - it's one of those "cliches" that don't actually occur very often. And it's especially not something I'd consider a cliche of anime - games maybe, thanks solely to Final Fantasy and other JRPGs, but anime rarely dealt those kinds of villains. If anything, when I think of well known anime villains, they tend to be unsympathetic and *generally* not-pretty - characters like Kyubey, The Major, Gihren Zabi, Kazutaka Hyoudou, F/Z Caster, Gilgamesh, Manami Tamura, Light, Charles, etc.
If anything, I'd argue unapologetic arrogant sociopaths and manipulative warmongers are more cliche in anime than tragic prettyboy swordsmen. Why do you think Wakamoto is such a popular VA? It's not just his voice - the roles he takes are very important as well. The only silver haired prettyboy swordsman anime villain I can even think of is Vicious, and he wasn't exactly tragic. I mean he got his girl stolen, sure, but he never seemed to give that much of a fuck about that so much as the fact that Spike betrayed the organization.
When anime employs the whole tragic character thing, it's rarely for a guy nowadays, or a villain. It's generally for a cute girl and it's a thing to try to make you feel bad for a character so they're better waifu material. In fact, in typical Seinin action series nowadays, the male tends to be an everyman underdog with little to no combat ability, while the girls are the ones that are extremely powerful.
