So, conceivably, you could have a deck absolutely riddled with Cids
In addition, various builds of Control decks in Standard just have inherent artifacts in them, making it so you can have a vigilance lifelinking Ezrim at any point in a game
Baba Lysaga, Night Witch and Glissa, the Traitor come to mind, the key being getting that second land without actually spending the mana to sacrifice the artifact
Usually it's fantasy, like Lord of the Rings, or sci-fi like Doctor Who and Assassin's Creed, but sometimes we also get something a little different, like SpongeBob SquarePants
In particular, Hall of Storm Giants is a great early land drop that can close out games quickly, helping controlling decks turn the corner
These dont have a price on TCGPlayer yet, but I believe that theyll easily hit the 1,000$+ mark judging by other serialized cards WotC has released in past sets
