Now it's balanced, assuming Passive Permanents (pillars/towers/sundial) are not affected.
Which they are. The point was mass PC, with denial as a side use.
The whole issue buddy, you're trying to combine two very different purposes into one card.
This is massively OP in its current form.
If it was simply soft PC to ONLY activated permanents, this would make a lot more sense... but this is so many effects at once...
1)Soft PC
1a)Impossible to counter once activated(It could be destroyed, but any permanents that had already been affected would still be affected until they lost delay status)
2)Counter to permanent protection(currently a non-existent feature)
3)Hard denial to quanta production(this effectively cuts production down to 1/3)
3a)Even if it were to follow the idea set forth by the linked thread(production cut by delay duration), it is still massively OP, perhaps even more so... The effect would take longer to accumulate, but effectively you'd reduce quanta production by one per turn until they eventually lost all quanta production.(By the assumption that this would stack each time quanta was produced, which by current wording it would have to.) Now this might not seem effective in a worse case scenario, but rarely would the opponent have more than 6 or 7 pillars by time you could play one of these.(Worse case scenario being the opponent has aprox 10 pillars before you play this at which point the denial is probably not having as much of an impact)
