Not all of us play Aromage, although it is quite common. I happen to be playing Krawlers for this event, and so long as I don't get paired against people who open double Squire into double Sunsaga or the occasional invoked Purgatorio while I have no backrow, I'll be fine. Already at DLv 13 from Lv 3 and also playing with only 1 Pawns and no extra deck. It's not perfect, but it's been working well.
Aromage has so many decision making to do, also just scoops when you lose your backrow. Shiranui is the best F2P deck, go through the mini box twice, then get 3x ballista, floodgate, fiendish, Karma cut. Perfect deck.
When you use aromage deck you have to face both your opponent & time. Although I like the deck, I never use it since the duels take TOO MUCH. And then a Sunsaga comes and you just scoop.
