Genbu (30b)
Unliving.
Attack: 10N
Tower: +10M
N = Quarry
M = Enemy quarry

I think this is a very interesting concept, as I already said on another thread, but it's quite strong. With normal quarys (3,3) it would do 30 dmg and +30 Tower. Playing Wonder with normal quarys and afterwards this card, would do 80 dmg and +80 Tower! I know this may seem to be an extreme scenario but it's not difficult for both players to have quary >4 especially in long mode.

I'd suggest to either cap the tower gain or reduce it to half (+5M).

There is Phoenix that can do 160 damage for 15 gems and 10 recruits. There is Seiryu that can do a really devastating damage without any limits. There is Colossus of Kran - 60 damage and +4 quarry almost for free if played on Unliving token. There is Spectral Dragon that can return third of 40 gems and 50 recruits, give you 20 gems and deal 150 damage. There is Rainbow Dragon - ~ 64 damage and +1 facility for free. There is Dragon Squadron - guaranteed 200 damage.
I can understand if you'll say that Genbu doesn't fit Unliving keyword. But it is definitely not overpowered, because it is at par with all cards I listed above. Or they are overpowered too.

I understand what you are saying but my objections are not about the Attack rate of this card.
Actually this is what I like about this card, and what I think is missing from Unliving: a good attacking card.

My objection is about the high tower gain. As I said +80 Tower and 80 attack, is very much. It's construction plus destruction victory at the same time, in short mode...

I feel that if you draw both this and Wonder in the same match, you should be welcome to your +80 tower.

Likewise, if you're playing against an Unliving deck and you steal this Rare via Princess of Elves or Illusion, you should be welcome to your +~60 tower, give or take.

I could accept having the multiplier toned down to 8M rather than 10M, though.

I also wanted to note that due to Obsidian gargoyle, I'm often reducing my opponent's Quarry to 2 or 1 while playing Unliving. Then again, others' Unliving decks may not take all of the attack cards I do.
