I think its OP. If you have an aether creature in play, then it is self sustaining. And is this stackable? If so, DEFINITELY OP. This can just generate WAY too much quanta. Perhaps it needs a cap of 1 per element, or a max amount of quantum it can generate a single turn. btw, i like the idea, I just have a feeling it will be too hard to make it balanced.
Actually, I had envisioned the maintenance quanta would be consumed first, then the creature quanta generated last.
The obvious remedies would be:
1) destroy/steal this permanent
2) kill/rewind aether creature*
3) drain quanta (e.g., pest, black hole)
*Yes, there are immaterial aether creatures but they are expensive: immortals = 6(7) and dragons 13(14). That wouldn't make for a very speedy deck. Sparks wouldn't work because they die right away. Phase spiders/recluses are the best bet for early play but are targetable.
Let's say you're playing a rainbow deck: how many rounds/cards do you need to get your "OP quanta factory" running?
A) 3
for upped telepathy + 3
for the spider = 6 quanta and 2 cards but creature targetable.
b) 3
telepathy + 3
for spider + 3
for quint = 9
quanta and 3 cards. Permanent still targetable.
C) 3
telepathy + 3
for spider + 3
quint +1
PA = 9
1
and 4 cards. That's a lot of work to generate 1
/turn in return. In order to maximize the payback for this card, you have to play lots of creatures and you only get 6 quints in a deck so creature control and/or permanent control are still effective.
This may be more powerful in a duo deck, though I haven't thought of all the possibilities. Of course, I'd be happy to hear any comments you have about how to better balance the card.
