You know Shivan Dragon? previously thought to be the most Trope-matching, hard Core (set) card in all of Magic? The Fire Breathing Dragon Archetype? Try again. The most Core Set worthy card is the one that matches the Trope that started it all: The Ring of Power. It's a shame they won't likely let it near a modern Core Set :/

Forget for a moment preconceived notions. Just Rethink Possible, in the far extreme--How AMAZING would it be if Wizards rounded up their best geniuses with the specific agenda of setting up Standard to be a safe, good place for Sol Ring to live, one last time? Like Lightning Bolt? A logistics nightmare? absolutely. Worth the effort of doing, if it can be done 'right'? equally absolutely.
