Name somewhat taken by the very iconic White Knight.

Ignoring that... this seems like a nicely white knightly ability.

I'd also suggest ditching the adding of hexproof; it doesn't seem like it would matter often enough, and is pumping up the cost for it.

I take it what you're saying, Vitenka, is that regeneration is nice, or hexproof is nice, but both are redundant? It certainly does make the card more powerful. Does it make the card more interesting? I'm not sure. I can tell you that it makes the card not a common, though, since, while the ability itself isn't confusing, trying to remember both modes while monkeying with the rest of your game is confusing.

Well, they kinda massively overlap. But regenration protects you from combat too, while hexproof protects you against nerf-enchantments too. So having both just seems a big overlap, and a bit too potent. And yeah; sadly, I think either on a third party is "Not a common" nowadays, but since this doesn't have a rarity defined, I didn't want to mention.
