Hm... I understand! I'd be happy to do that. Duelling with his deck is fine, but using it for something like that would be kind of troubling even if it wasn't designed pretty much entirely to lockdown opponents.

[Oh, that's right, he hasn't explained it...]

The Occult Deck he used to use and the Lockdown Deck he uses now are both designed to render the opponent helpless. It's neither fair nor particularly useful. So it'd be better to make a separate one anyway.
