As I noted previously, the Mirror of Mystery Adventure Pack was officially listed as being part of the Wave 2 launch for Skylanders: Trap Team, but did not appear in stores as originally expected.
On Friday, October 10th, I was finally able to obtain one at my local Best Buy. Rumors stated that Best Buy had a limited 1-2 day window for exclusivity with this release, but this information was never independently corroborated. However, as of Sunday, October 12th, the Mirror of Mystery Adventure Pack was reported as readily available for multiple Toys R Us and Target locations in addition to Best Buy, so any exclusivity expired quickly.
For those who have not seen this pack yet, I have posted a photo below. If you are not yet able to find this adventure pack, don’t despair, as this is only the beginning of Trap Team’s cycle and all characters, traps and adventure packs will be available virtually everywhere within the next couple of months leading up to Christmas.
