Why does this keep getting reported as if there's some special affiliation with this paper and WOTC? The holofoil they used for Base Set, Jungle, and Fossil (and Legendary Collection) was "their own" holofoil and it looks pretty lame. The holofoil they used for Base Set 2 and Rocket-on is closer, or presumably identical, to the holofoil paper Japan had been using since their First Expansion Pack in 1996.
By looks, the article seems to be talking about the Japan-originating type of foil, nothing short of insider knowledge would point towards the assumption this holofoil is proprietary to WOTC.
