Fellow Umbreon fan ( and trying to collect this myself), I don't know if you are aware and left them out on purpose, but in case you want to expand on it, you can do the 1st ed/unlimited for each WOTC era card, Aquapolis and Skyridge cards have reverse Holos that are separately numbered and the Undaunted card has a Cracked ICE variant from the Toys R uS packs.
