We now have images of the previously mentioned Darkness Abalze Premium Checklane Blister.
These 1 pack blisters cost $6.99 and feature along with 1 Darkness Ablaze pack, a TCGO Code, Coin and 3 cards with an evolution line. The blisters will release alongside the Darkness Ablaze release on August 14, 2020.
This product contains an evolution line from the previous Sword & Shield set. With Rebel Clash, it was Galarian Obstagoon / Gengar. The promo's shuold contain the regular holo pattern, so no cosmofoil holo. It's a straight print from the set.
