Interesting suggestions, I actually did tried them all before. However, my personal opinion is when you put those kind of cards, it actually changed the feels when you are playing the deck. Of course it will be faster and really strong but I will try to stick with the zombie theme. And for Spine of Ish Sah, it is a strong card in a way, but we do not have a way to actually interact with it in the sense that we cannot sac it so it feels like it is less effective. But if you guys are interested, feel free to take out a few utility zombies and slot in the suggestions by Mr BurtReynolds. Thank you very much !!!
