Buster Blader is just one of the many decks that can work. Not sure if it's still needed after they nerfed the challenge. I took out many UR/SRs in case you don't have them. You can always use the "extra life" item or add stall cards to help you.
You only need to beat the challenge once, if you haven't. I strongly recommend you to use items, add some Field Barrier or Closed Forest into your best deck. Stall at wave 1 with your best atk/def monster and don't proceed to wave 2 until you draw into the right cards and are ready. It should not be that difficult.
