How about if the card was changed around a bit? (Hopefully not changing the main purpose of the original too much)
"Your opponent can't store more than 15 quanta per element. 12 if mark is . 1 less per card, up to 6."Numbers can change, but the general idea is there. It's useful starting from the first one put in play, as opposed to the current one. However, you still need a handful of these in order to get the full and better effect, so getting an
mark helps with this. It does shutdown a bit harshly decks that depend on high quanta usage and storage of a few elements IMO once you get most of them out,
compared to the current one, and it also seems like rainbows with cheap cards will probably get away with it easily. Maybe it should effect the total quanta, with the numbers being tweaked of course. I also put a cap to prevent abuse through double draws and mindgates.
What do you guys think?
