I'd go with what Roxas says here. Try to limit the extra deck (I suddenly feel like an ass over making all those Bountr synchros) and not have a toolbox.

I see Matt in almost every YGO RP I create/sign up for, and while I agree that addressing the meta is a challenge few GMs - if any - have managed to step up to, I specifically said the first rule is to have fun. If it starts ruining everybody else's fun, then definitely change it. Until then, do as you were doing.

As for you, Matt, if you'd like to join then feel free. If you're just here to talk about meta decks and how everybody seems to use them here, you've come to the wrong thread for that. I've already addressed my case on the matter.
