A new type of card is going to be introduced into the TCG soon. It is called an ACE Spec card and it has a special restriction. Each ACE Spec card can only have one copy per deck instead of the usual four. The first two ACE Spec cards are named Crystal Wall and Crystal Edge. Crystal Wall makes Black Kyurem have 300 maximum HP. Crystal Edge increases the damage of White Kyurem’s attacks by 50. Promos of the Musketeer Trio are going to be released to commemorate the release of Kyurem vs. the Sacred Swordsman – Keldeo.
