DUke: Now that I can agree with. But let's take it a step further... suppose you don't know if there's a way to make your deck stronger (yet). You either try to think of a use of a card or think there's an even better or alternate way to improve a supposed winning deck. So you build, test, and rebuild some more. Basically the "traditional" idea for either a rogue deck or an upcoming tourney deck, but using cards that the current establishment are not using (the best that comes to mind is Donate/Illusions). Now is this process of seeking to become better mean you're competitive and not casual? Say you take Battle of Wits and win with it constantly. Is it no longer casual? The card that you win by having 20 creatures in your graveyard? In other words, if the deck is not well-known in tourney circles and thus on decklists everywhere, how do you know YOUR deck is not the best it can be? Yeah, you could test it by proxying up the well-known decks and seeing if it wins, but what casual player does that? All you know is that you have a deck that you play in your area and it wins fairly often. Not all the time (what deck does?) but enough that you don't want to scrap the idea and that you're having fun.
