Umm suggestion?

Maybe allow Duelers to change decks between matches for when they test. You only get to see one side of a person's ability to duel when the option isn't there. Also, rash judgments could be made about an opponent that way ^^

I don't know but in a test you must use your best deck or the decck you handell very well let the testers think aboutt this but as I know them they will say no

Of course - no.

But it makes the system very flawed ^^;;

I'll lock this but first think of this : in real life at a test lets say at math you see a exercice that you don't know how to do it but you know to do the harder ones do you think your teacher will care i don't think so
