THIS.Poison should be in 1 faction only and must have higher provision costs
I agree with higher provision costs. But shouldn't just be one faction. RIght now, poison is too cheap and too abundant. Every NG deck is running some sort of poison variation and it's pretty dumb if you face them all the same. I even added shupe inside my monsters deck due to the need to destroy their "balls" twice.
They probably will be adding some poison immunity buffs next expansion or so. Kinda typical of these card games, imo.
