Bro, you need some more cards. If this is the best you got then start leveling up some characters like Mokuba and Kaiba. Can combine their decks for a nice dragon deck.
Easiest decks to make are magicians deck with Yami.
My advice. Clear the mini boxes. Aim for Super Rush Headlong, Wall of Disruption, Regretfull rebirth and Chalice. Get some 1900 beaters. Level up Mai and Odion for their defensive traps. That's an upgrade to your deck right now.
If you're going for a lotus deck. Lotus is priority ofcourse. Get one (or 2) asap.
