Pretty simple! I haven't tested it yet because I was making custom cards and made one that was basically the same as this without realizing it, but my custom version works fine.

i dont see why it wouldnt be 100% if you added "attacking" to it...
Sharding Sphinx is codable now due to Zeth's huge update on rev2444.
Note that you can only play it if you are playing with rev2444 or higher. In the last official release - Wagic 0.13.1 - Sharding Sphinx won't work as it should.
