What a broken card. This needs to be banned because photons are absolutely too strong since you can easily bring out GEPD and this card for a turn 1 OTK
Photon decks can't do nothing vs a turn 1 photon bouncher or slash harpie lady, two of the most common monsters in our meta. Also book of moon on Galaxion is also an instant loose with 0 comeback moves. They just surrender.
Canadia, floodgate, fiendish, karma cut etc etc etc all just shut down the deck. Also the deck has 1 linear play and no comeback moves once it gets interrupted.
It is powerful, but far far far far away from being tiered or broken.
