Pokemon Black & White Boundaries Crossed Spoiler - Crystal Edge

Crystal Edge 

Black & White—Boundaries Crossed introduced a new type of Pokémon card, the ACE SPEC card, of which you're allowed only one in your entire deck. Not one of each kind—one ACE SPEC card total, so you better make it count! The first we'll look at is Crystal Edge (138/149), a Pokémon Tool that attaches specifically to White Kyurem-EX. When Crystal Edge is attached, all of White Kyurem-EX's attacks do an additional 50 damage to the Defending Pokémon! Dragon Stream alone will do base 110 damage, and Ice Burn will do an unbelievable 200 base damage! If you plan to use White Kyurem-EX in your next deck, do not forget to include Crystal Edge to give you even more knockout power!

Pokemon Black & White Boandaries Crossed Spoiler - White Kyurem-EX

White Kyurem-EX 

Fire and water usually don't mix, but when you attach the right combination of Energy to the new White Kyurem-EX (103/149), you're ready for some devastating power! Do damage and add Energy to White Kyurem-EX at the same time with Dragon Stream, a 60-damage attack that will also let you take a Basic Energy from the discard pile and put it on White Kyurem-EX. You'll be happy to have the extra Energy when you use the Ice Burn attack, which requires 2 Fire Energy, a Water Energy, and 1 more Colorless Energy: Ice Burn does 150 damage and burns the Defending Pokémon, but you have to discard 2 Fire Energy attached to White Kyurem-EX. Get that Energy back out of your discard pile with Dragon Stream and you're ready to keep the heat on your opponent all match long!
