Seems a bit unbalanced that both didn't receive a Jirachi engine considering both builds use it as a staple draw support.
An odd thing I noticed was that both receive 4 Pokegear 3.0, which seems to make sense in the ReshiZard deck as your searching for welder constantly and needs the support as its lacking Jirachi but 4 Pokegear in the PikaRom deck seems a bit excessive. I understand its a great card in a certain situation; Mallow/Lana for heals, Prof. Research for draw, Marnie for disruption but without Volkner its seems a bit of a space-filler.
It's quite evident of the lists that they are trying to give as much play-ability for our money by including cards that will survive rotation but the lack of Prism Star presence in the ReshiZard deck paired with no Jirachi engine it just seems a little unfair and overall disappointing for those who could only afford the one and are almost forced by current meta to purchase one deck over the other.
Overall PikaRom has received some of the best cards that were printed in the RayquazaGX deck as well as the shining factor of the Ultra NecrozmaGX deck, the Jirachi core and has evidently come out on top as the superior deck. for your money as well as viability of the two.
