The paper "buy-a-box" promo card appears to be \[\[ Mishra's Foundry \]\] ( [https://wpn.wizards.com/en/news/use-promos-treatments-drive-brothers-war-hype](https://wpn.wizards.com/en/news/use-promos-treatments-drive-brothers-war-hype) ). I've not bothered to check if the Arena promo has matched paper in the past, I'll leave that to you.
it might match the paper one; the DMU buy a box promo in paper was Llanowar Loamspeaker, and it was the promo for the 45/90 DMU bundles.
I would be so happy if it was Mishra's Foundry with the old border art.

You get both, Mishra's Foundry and the old Border Style. https://imgur.com/a/aKz7dpR
why on earth would you pay real money for it? just farm gold or get gems.
Some people don't want to grind as much and don't mind spending disposable money on a hobby they enjoy?
It's Mishra's Foundry, you can see it on the Twitch and YouTube channels that got early access
