It's a reference to one of my comic book guilty pleasures The Legion of Super Heroes
Fable of the Mirror Breaker is now worth more than $20 and, given its presence in the deck that one the most recent Pro tour, it probably wont be slowing down any time soon
Sidisi, Brood Tyrant, Omnath, Locus of Rage, and The Gitrog Monster are the first decks that come to mind
FromTheShire: Extremely cool to get a Gate Commander so we can follow in the footsteps of other formats and turn Gates from a meme into a real deck
Ethereal Haze There are quite a few white cards that allow you to prevent damage from specific sources, or under specific conditions
While likely a Goblin Kindred card, it will probably slide right into a Krenko, Mob Boss deck
