1) I am not sure if negative attack is weighed equally with positive attack. It is a decent assumption though.
2) I think snake bites hurt. Having a negative attack seems to indicate that snake bites are soothing. This does not compute.
3) Venom that can hit is worth +2 not +1
4) Upped cards get between 1-2 points of cost reduction normally (Most stick to a 1 point reduction)
5) Life creatures get a -1 cost reduction.
6) I agree that Deadly Venom that can hit is worth 3. (Venom that can hit is worth 2, Deadly Venom is worth 2)
7) I love how poisonous this card is! Perfect synergy card between Life and Death.
8 ) Neat Picture
Unupped
Cost = -2 (Negative attack) + 2 (Poison) +2 (Venom that can hit) +1 (venomous) -1 (Life bonus)= 2
Upgraded (Attack increased to -2 to get the cost of 2
)
Cost = -2 (negative attack) + 2 (poison) + 3 (Deadly Venom that can hit) +1 (Venomous) -1 (Life bonus) -1 (upgraded) = 2
