I've been playing with this deck in TCGL, and so far, all my opponents have either run out of cards in their deck to pull, or just forfeit the match when it was clear they were GOING to run out of cards. The basic win condition is having Manaphy, Vanilluxe, and Radiant Alakazam on my bench, while Tsareena EX is in my active position. That way, I can prevent my opponent from using any attacks, and thus run their deck down to nothing OR take out their Pokémon one by one.

Are there any glaring weaknesses? Anything y'all would recommend improving? Any input would be vastly appreciated.
