I like this for an alt shield for Entropy in regards to a chaotic effect could happen, but I would think of it more like a perm pandemonium versus a alt skull shield.
So how about the idea of: unupped 7x(
) cost, 0 blocked damage 40% chance attacking creature has negative status effect occur on attacking creature, 20% chance a positive status effect will occur on attacking creature, 30% chance a spell will reflect, and an upped version is 7x (
) cost, 1 blocked damage, 40% chance attacking creature has negative status effect occur on attacking creature, 20% chance a positive status effect will occur on attacking creature. 30% chance a spell will reflect.
