Comparing it with prosperity it lacks the restoration keyword and the "negative-opponent-pushing"-effect, if stock is lower. I think, it is very similar to the first... nevertheless, I "feel" it is weaker... can't tell you exactly why ;-)

Actually it's stronger in zero card deck. You get to lower your own facilities, spent some resources on preparations and play catastrophe or soul cleaver/etc

If you want to lower your own facs, there are quite more useful cards in lower rarity and higher (positive) effect. I'd never put that card in my deck, to lower my facs O__o
If you plan to play Catastrophe, it would depend on the situation, in urgent cases, prosperity would be better: with prosperity your opponent might get stock as well and your gain isn't that much (=hurtful) ;-)

I see the similaritys between both. Maybe i have to rethink the condition...

What about Facilitys => enemy facilitys?

Edit: Changed it to a tower based concept

Scroll of the moon; Rare; zero cost

If #Tower => #Enemy tower:
Facilitys: -1
Always:
Tower: +20

Yeah, now the concept is unique...
however, it's effect may be a bit weak: compared to uncommon orc-engineer (tower: +17) it's possible negative effect is 3x as strong.
However adding even more tower+ would make it a finisher, then facs-1 won't hurt :-/

Also possible card to compare with: enlightment: both towers+25, both all facs+1

what about adding: summons non-common tower+ non-support-kw card? Or summons one of the "moon-cards"?!
As the moon-theme supports is discarding/zero-cost/no-keyword, it could also discard all keyword cards (can't draw rare) or something (sure too strong!)
or just adding some wall, too??

Well, i don't like to overload on text,so i could see that the card coulradd wall as well.

Edit on the card: +10 Wall
