Candidate for a build around uncommon

Can we call a card in a duel deck build around?

These cards are ostensibly real cards from a set. So the slot is for a build-around-uncommon for the hypothetical draft environment these duel decks are built from.

In the deck itself, I think providing the U/R deck with an alternative to combat damage is important when the G/W deck is going to be gaining tons and tons of life.

Yes the alt win ability is important.

As for why I want a build around, its because duel decks should have "hooks" that grab a new player's attention and make them want to edit the deck to work around that direction.

Some players enjoy deckbuilding to a large degree and so even though this is less likely with a custom deck its still nice to hit that niche audience especially when its already doing good things for the card set.

PLAYTEST: This card ends games. All the artifact( token)s lying around and waiting to be tinkered into something useful suddenly become a win condition.
