Yeah I know that. I still think it can cost for free, sacrificing a creature just for drawing A card. The upped is fine though.
I disagree. Each one creature I play becomes 2,3,4 draws with boneyards in play, and that doesn't even count that I can get skeletons from other things.
This is my problem with it:
Lets say that I have a hand full of kill cards. Every time I use one, I kill a creature and get a skeleton. I sacrifice that skeleton to draw a card. Every CC card I have now gains the ability to replace itself. This would ruin almost any deck, as no matter how many creature cards you play, I will never run out of CC in my hand.
I think I'd be ok with it if it was only once per turn. Even then it would be a strong card.
My recommendation- keep the costs where there at, and get rid of the multiple uses per turn.
