I don't think it should be dismissed so quickly. I actually see potential if you interpret it right. If ALL sources create EXACTLY 3
. Then it is actually a powerful anti-rush card. This greatly reduces the rush potential of cremation and nova which rely on the large amount of quanta being generated. This way they only get 3 quanta total so they have to wait to make their move or suffer greatly diminished returns. To prevent being OP against mono's make it only last 2 or 3 rounds. This again reinforces anit-rush properties.
There is also potential for synnergy with shards. Even in a mono, since in 2-3 rounds you will have all the quanta you need to power them.
May still need some balancing work though, perhaps make cost
and
instead of just
and
.
