There is definitely going to be a need for some low-mana immunity cards that can also do some damage. Or possibly even an immunity summoner forthcoming???
I would also like to suggest that poison shouldn't work on monsters who still have shields. Seems a little silly that I blocked the blow but somehow I still got poisoned. And monsters with Divine Shield certainly should not get poisoned until its used up.
I love the new card although I'm with the 99.9% in believing the bots are going to get the cards and I'm sure some will get multiple somehow.
