If you don't already have Dream Radar on your 3DS or the funds to buy it, you can still add funds to your 3DS EShop account with EShop Gift Cards until the 29th of August this year.
Dream Radar only costs $3 USD and the lowest an EShop Card can cost you is $10 USD, which is just enough to also use Pokemon Bank which costs $5 USD annually.
