Ok, so going through this I'm seeing a few problems. First off, your running 3 vanguards, which is a bit of a dead draw and discard most of the time, cut it down to at least two.

I would also take out the Galaxy-Eyes Photon Dragon, it's a creative idea, but again had no discard ability, and in lots of games your only going to have your grapha on the field.

And finally, 3 Trade-In. I would cut this down to 1, unfortunately, your not always going to be drawing your grapha, resulting in Trade-In being useless.

BTW, Trade in is a cost
So you dont get his destructive capabilities

I see a problem with this, the fact that it has not be submitted to an admin for approval, therefore it is being moved to card and deck discussion.
