so I still have yet to lose a game of blight, (although a pretty nasty error is making that a distinct possibility) even on nightmare.
One thing I feel that is very strong is the play a card/get a card mechanic. It allows for players to snowball mid/late game far more effectively than the undead meaning they can easily come back from being behind within the right deck and draw.
What if you only drew 1 card every x hours up to x cards? you could still spend 2 Valor to draw a card, but you would no longer draw a card whenever you played one.
Perhaps some cards would still replace themselves, but it would be an ability like Lurker.
Just a thought.
