Latest issue is out and comes with 2 packs of power discs all for the price of the magazine.
Mine was a pack from wave 1 & 2 of Disney Infinity 1.0 so if you're just joining with either of the 2.0 starter sets give this a look as unlike 1.0 you don't get a free power disc with your starter set.
Oh before i forget the 1.0 circular power discs should work fine with the 2.0 Marvel Playsets.
