it to me is like a mixture of parasite and thorn carapace that has been strongly nerfed, only poisoning one creature, and that one creature is going to be the first one that was played most of the time, i would say make it a 100% shield that absorbs quanta but
1) fire shield is 100% but doesnt poison, so that may not be nescessary in the arguement
2) i consider fire as one of the highest quantum producers, needing a lot of quantum to fuel it's cards, so it wouldnt make a difference for it to absorbs say 3
a turn
