Original card.

Card #2 in the 'toughness matters' uncommon slots. Since this strategy is supposed to be in white, I was leaning toward this being a white enchantment. But it seemed weird choice with Feast of the Unicorn in the same set. Hopefully, the overlap won't be as noticeable as a piece of equipment. And I'll have to live with green drafting these away from the white player on occasion.

As with any scalable card, this is hard to cost. My reasoning was that Vulshok Battlegear is a reasonable uncommon piece of equipment, and +3/+3 is about equivalent to +5/+0. In a normal deck, a five toughness creature is a little on the high end... you got to work to make this worth more than it costs. Though, not too hard.

All I know is that any card that makes Kami of Old Stone look good is cool in my book.

I like it.

I love toughness-matters. I just came here to say that Vulshok Battlegear is considered rather above the curve; there are more recent cards that are strictly worse like Greatsword and Warlord's Axe. Which is fine and doesn't actually interfere with your point.
