Hm actually quite interesting. It's not bolt on a stick but could be and it can also be used as protection, I like it. However like most of your cards Odin it's up and deserves a cost decrease of at least 2 on both ability and card cost i think. I agree that it's better to start up and work towards balanced ( thats also how Zanz works ) but sometimes you go to up.
But overall you are really good at finding new mechanics.
Seems a bit UP? Skill cost should at least be equal to gravity force cost (2|1), maybe 3|2 if reusable GP seems too powerful (it doesn't to me).
Voodoo dolls can make gp on a stick fairly abusable. I can bring the skill cost down to 3|2 though. I aimed a bit high just to be safe... I just don't want to see voodoo trap rushes becoming TOO easy.
I don't know if that would be so abusable? It demands at least a trio and that would cost speed and even then it would have it's weaknesses.
