Wow Luxray could be decent! If you go second, you item lock Turn 1: if not Volkner for Candy for Luxray turn 2.
Unless I'm wrong...
I'm so sorry, It may be premature to cite rulings of unreleased cards like Luxray, but as Shrine of Memories cannot look back at Stage 1 attacks if you skip Stage 1 by rare candy, that means one can assume, but not 100% confirm, that if you want to lock w/ Luxray, you need Luxio in order to use the effect...
^ If the above is true, then Shining Celebi's ability should NOT work w/ Rare Candy+Luxray. You more than likely need to evolve Shinx manually/Wally to Luxio first for reference purposes...
