Yeah, well, the point wasn't to strengthen monos - as that would require this to cost random quanta, and while that could be an idea for the upped version it is not the case - the point was to give Light a quanta disrupting tool. This can hamper any non-mono deck quite seriously, but the effect it has on novabows and immorushes is terrible. That is intended as I like variety and I would like to see more intresting decks be used rather than rush muscle fights. Reducing the power of nova and immolation is part of the charme this card had in my mind. If that is seen as a bad idea, I can change it to:
"Pillars and Pendulums produce quanta matching their owner's Mark"
But that still leaves Quantum Pillars. I don't think it's a good idea overall, I prefer just stopping quanta production altogether.
