Yugioh online dp usage?

It is actually bp now not dp. But I would recommend picking up the in game starter decks as they will give you some of the staples such as heavy storm. The cards are for the most part found in the packs they come from in the actual game. Some of the cards such as Allure of Darkness were a prize for taking part in some of the in game events such as Gunslinger or Duelist Trial. The good news is if you stick with it after you have enough TP you will be allowed to select one card every few months. If your really good you will be able to select more than one.
