Azure Ace Starburst is awesome. She built the best Casino in Las Haygas, she rose to power and became the town's leader in all but name, and she has two amazing foals. These foals need a tutor, and Ace knows the perfect pony for the job: One she met once and never spoke to again, but just happened to become the most magically powerful being in the multiverse.

Look out, Ponyville. The Aces are coming to town.
