Is Shadowcat good? I see it being played a bit, but don't know what's so good about it. Is it good in Joust, Melee?

It isn't good. The old Syrio is way better, and the same price.

Thanks divinity!

Why is my post black in color? O_o'

Depends on how much stealthy military or how many Shadows cards you need. There are certainly shadows decks that I would run a couple in as 0 cost ways to trigger some of my effects like Alchemist's Guild Hall and Black Cells.

He certainly has his uses in a Direwolf deck as he hunts with the pack " At Night They Howl "

It's also non-unique, which is a plus (still, right?)

However I don't know if I've ever built a deck with it. Hard to justify a single icon character, can't be reduced (shadows needs gold), tough sell.

I'm a pretty big fan of Shadowcat in heavy shadow builds. They're a nice chump block, and the stealth helps you bypass the defenders that you don't manage to hit with your control. They also don't have bad traits, and can't be one shot by Flame-Kissed.
