@patdk75 The amount of environments are the same thats true but the cost isnt for almost all. True frenzy and double strike is simalr besides the fact that frenzy allows zombies to destroy all targets if they have the atk for it and then atk directly i assume this is a counter for team up as well though. It always seems that zombies are more favored when it comes to similar abilites/cards
For example:
Cornucopia->10 and spawns plants in every lane now i never have played this card or even seen it in play for some reason but im assuming it spawns a plant in a uninhabited lane unless it spawns a plant with team up? (Not sure) while zombot -> 9 destroys all plants if my first theory is correct then zombot has an advantage at a lower cost
Lurch for lunch ->2 bonus atk. Plant food -> 4 +1/+1 bonus atk. I dont think an extra two cost is worth the bonus in stat especially if nimble takes away these stats AND heals your hero by two for a measly one cost.
Somhow though area 22 ->3 frenzy +2/+2 which is like coffee grounds ->2 dbl strike only cost an extra energy for their bonus stat
Now i can keep on going as there are more but i think you can see my point. I mean the fact that 5 zombie heros are a brainy type there really should not be such a lower cost for their cards if anything it really should be the other way around
Im sorry and i know it seems im biased but there are just plain facts that cant be ignored.
