So far it looks like we have only one store championship for the area. Nerdy Stuffs is going to host a regional event with the chance to get to go to the nationals at Gen Con.
The first 32 participants get a foil Fluttershy, Rainbow Chaser card. The top 8 get a foil Cloudchaser, Flexible Flyer card.
The entry fee will be $15 plus tax. They plan on having more prizes during the tourney, but they're still nailing down the exact details on that. Also, they are doing pre-registration at the store itself. There isn't a cap of 32, but if you're within range of the store you might want to lock down your promo card.
