But poison is for death, not for life!
Yes, but too much poison for life wouldn't be very good.They could be two element for poison, but life and death are two opposite
You're right that the most of the cards and abilities with poison effect cost death. But there are two cards without death: Carapace and Puffer Fish, so poison isn't death only.
I want to keep death out of the idea because the cards have a strong synergy with death (Bonewall and Vulture) right now and I want to have a flexible card.
I like the card idea, although it would create an unreal synergy with Bone Wall. Running these to kill your opponent's creatures while sacrificing themselves would give you so many bone walls. Add a Fallen Druid and entropy mark and you can turn the ones you don't need to poison into awesome mutants.
That is the biggest problem I have with the idea, it works to well with death.
A way to change that could be that sacrificing the Bees don't affect the Bonewall but I don't know if it would be possible. Maybe the sacrifice could work like rewind but it doesn't put the Bee back in the deck.
I could also modify the ability of the Bees so that it can't use the ability so fast or that it work in a different way. ( Like you have to sacrifice N Bees to kill a creature with N HP. But that shouldn't be possible with the code.)
