I'm not sure if this has been done before or not but I was thinking about this the other day.
We all know how a normal Shopper works - CAK. But what if there were variations to this?
G-Shopper (Ground Shopper) is something I thought of. What you simply do is replacing the Attack From Rope rule with a Attack From Ground rule. You go hunt your chests, preferably with rope of course. Then you must attack your opponent from the ground.
I honestly find this to be even more difficult than doing it from the rope.
I suppose you could make a hybrid with G and normal shopper to allow both too.
Just a thought
