The problem with ranking XY is that a lot of sets are ´good´ in their own right. FlashFire has it´s fans and haters, just as Evolutions and Breakthrough. But yeah, give me FlashFire. The biggest problem with those later sets is that, at the time, there was soo much product.
The card artwork in that era is extra “busy” even by today’s standards
