Well, find a card on whatever clan it is you are using within that budget.
Budget DT deck V.2
Uppers Hugo and Montana Hugo are the best for begginners
With those two deck you can manage to get in the top 150 without even trying just by playing the whole hour.
Just chose one . Start buying the cards from ther cheapest to the most expensive. You can also buy other characters from those clans who arent in my presets like Fabio or Samantha and do some varitations
Hope I helped!
