It seems like Toywiz is all over this pony thing lately! Up on their site right now are both booster packs and boxes for pre-order. With a release date of July 15th, we should be flooded with pony cards at meetups and conventions in the not so distant future!
Head on over to this page (30 Count - $49.99) for the box, or this page for the boosters (5 Count - $8.99)!
Remember, every Trixie and Cadence you send to me earns you +5 EQD points. What do EQD points do exactly? Accumulate them and find out! An announcement will be made in 32 years from now.
