I played a bit more; either both Heaven decks are broken, or I'm an idiot, or I was just unlucky. But the Earth deck for Rune and the suicidal one for Shadow were a perfect ten. I haven't really played Blood with the mouse deck yet; I guess I'm still worrying about the absence of the Vampire Queen, without whom this deck isn't particularly great.

I use this thing as a buff for 4 mana; the rush from it is almost unnecessary. It has saved me more than once in that regard.

Good girl, works well on Earth. An excellent unit for its cost, and there are plenty of sigils for 1-2 mana in the deck.

I would give a lot to see the face of the opponent as Elana transforms into an elegant Clay Golem before their eyes. The poor guy practically had a meltdown and ragequit.
And in the suicidal deck, these guys basically made the game for me:

Very nerve-wracking. Especially when there's more than one of them on the board. Especially when units rush to kill themselves instead of hitting the leader. Especially when there are no AOE spells in hand.

Two corpses for the price of one, and they took almost the entire enemy board down with them. Also, I love the art for the evolved Lich. When I first saw it, it completely blew my mind.

Couldn't even make a move, but he aggroed the opponent, killed himself, and gave my other cards something to work with.

My new love. In the first few rounds, more than half my HP was gone, but then I played this guy and very quickly healed back up to full HP.

Didn't show his full potential, but I still consider him an excellent card. Ward and very annoying last words, and the counter doesn't always arrive in time.

My precious <3 <3 <3 My sweetie <3 <3 <3 The enemy had 4 HP left, I had one evolution point, and right then he summons a guy with Storm just as if on request.
