Deutsche Leute sind verrückt ^^ but by the way, I didn't comment the card.
I think it may be boring... pay 8, gain a nearly-ruins, deal 3 ruins... looks like a race-to-8 to junk both sides and one fewer than the other one. 6 isn't enough to me, unless you know you need that plague in your deck (lol).
Main problem : if there are 5 ruins left in a 2P game, you hit $12 thanks to engine or luck... game is over for opponent, right ? And it's even more unfair if he could pull out $12 on his next turn.
