Yeah I've been voting it up everytime I saw it. I still think some more weapons wouldn't hurt the game. This one introduces another very defensive weapon. As you only have one weapon slot, it also requires people to think instead of just spamming ordinary creatures or permanents. (apart from animate weapon ofc)
Same with Spine carapace and Jade Shield, I don't think it would hurt some elements to have a wider variety of weapons.
Sorry for going totally off-topic btw, I hope you don't mind!
