This shard is really boring..
If you want "denial". There is a lot of it.
Black Hole. Devourer. Earthquake.
This shard is not worth to have "shard" title.
It is worse than a flooding, denial of mass creature. "Have mass quanta, I am not scared of your mass creature..," it said.
It is worse than BlackHole. BlackHole is quick, denial and also healing..
It is worse than devourer. Devourer steal quanta, make enemy cannot use it, and also quanta generator.
It is worse than earthquake. Earthquake decrease the production, and this shard is only limit the production. Enemy still can produce it.
This shard is only limit the cap of quanta. Not useful in so many situations. Enemy can still use their card, so there is no denial.
And this card also have to played as many possible in the field. more card, more powerful. Very difficult to setup.
It is ok to make this card as NORMAL card.. But, i think "NO" if this card become a shard.
But, there is also limitation to this card, even to be normal card.
If this card effect became too powerful, such as "limit quanta to 0"!!
Then, the game will be very boring. (Consider if enemy use this card also, then no player can use the card, because the limit is 0).
In summary, I think this card should not be released.
Thank you for attention. CMIIW.
