Welcome Gustovo. Probably not going to find secrets to tricks here. I suggest getting an entry level card magic book to get you started on the right track. Royal Road to Card magic by Hugard and Braue and/or Magic with Cards by Garcia and Schindler are both good starting points. To preform you'll need a good deck and here's the place to find all kinds on information to help you in that decision.
Good luck in your journey,
