Mtg Magic The Gathering War Of The Spark Prerelease Kit
Inside, you'll get six War of the Spark boosters. Plus, a random stamped rare or mythic rare card as your Prerelease foil that could be any rare or mythic rare in the set! And you'll also get a stamped foil planeswalker card, which could be any of the planeswalkers in the set (uncommon, rare, or mythic rare)!
Then, of course, you'll get a couple other goodies - like a spindown life counter to keep track of your life total.
