It took over 3 weeks to guess this solution and my friend who knows nothing about computers gave me the idea. Thanks to anyone who tried to look up this problem and help solve it. When you go 'back' from the 'Deck construction' mode your deck will remain the same and from then on you will be able to play normally, at least I have for an entire day so far.

When you delete the file close the window and go back to your game. Some of you will be scared to do this but don't worry this particular file is saved automatically every time you make a new deck or adjust your old deck. start up 'my computer' or anything else that will get you a 'folders' option then branch out until you reach the 'Konami/power of chaos common' folder. He then became a main protagonist of the second-series anime and the. change the deck to make it the way you want it and THEN minimize the yugi game. Seto Kaiba started as a minor villain in the manga and became much more prominent later on. open the Power of Chaos game in a 'window' mode and then go to your deck construction.

then my friend said something I never thought about and I tried it. change the program deck in the folders/alter the name. Okay I bought yugi the destiny and played and played but never could get the cards that I won to stay in my deck.
