See Challenge # 108.

Very abstract; moons hanging close above, people digging; old fashioned ray gun. (Whatever were those rings on the end supposed to be, other than 'randomly futuristic' anyway?)

So guarding, or maybe attacking, a dig?

Finding ancient technology is very much a thing in sci-fi; we'll go there.

Feels like a rare to me.

After each untap step? As in "at the beginning of each upkeep"? Fair enough. Also needs to be "reveal" rather than "look at" for verifiability.

But terminology nitpicking aside, this is interesting. I don't think it's very playable. You sometimes draw an extra card, if your deck is sufficiently stuffed with artifacts, but at the steep cost of creatures on the battlefield. Unless you've got some token making that's not a cost you'll want to pay, which means this only goes in an artifact tokens deck, which isn't unknown but is fairly unusual.

Yeah; the glossary didn't give that step a name, so I took the liberty of simplifying S:tC by eliminating it :)

Pretty good with artifact creatures that have death triggers, too. But sure, it's pretty niche. S'why I made it rare. goes gonzo in multiplayer too ;)
