The rules for testers and testees need to be remade to ban any loops or broken decks. It isn't fun for the tester or testee. This isn't made to be "Who has the better loop and who goes first" Academy. If you get tested by someone, you're supposed to show how well you play, not which netdeck you chose. If you go against a tester using it, if they get the first turn you have 0 chance of getting into anything higher than Blue. I propose that deck creativity have a factor in a testing rubric that way it isn't 100% wins/loss'.
