Thank you both for your fast feedback!
One thing Blaze mentioned: The costs might be too high indeed. If I consider them lowered I have to refuse drake's statement 'being useless outside of rainbows'. You just have to be a little creative:
Cremation production is doubled (should even work with the actual costs). Pest production is doubled; and if it would also devour two quanta, as Blaze asked, there would even be one more aditional use. I like the idea
Gemfinders, RoLs, Brimstone Eaters and Damsels offer twice as much quanta as well. A synergy with Fractal is thinkable e.g.
So it's possible to easily benefit after a very short time from that card. In the later game it could be very strong if the *Lose all quanta when played* would be removed. You could easily push the damage of Siphon Life, Ice Bolt or Fire Bolt and the protective strength of the Dissipation Shield/Field for example. Not to forget the strong push of the Rustler...
Or *Lose all quanta when played* can be removed from the cards at all but the effect of the unupped applied to both versions (if destroyed, lose all quanta). Then it's fair to let the player keep it's quanta on use imo - and makes sense with higher costs also. Adds some risk to the card, and increases the importance of PA.
I hope for more feedback because I really see a potential in this idea with a wide spread of uses - and tactics possible with that card 8) And please don't be pissed because I didn't quote you 'properly'
