Hello dude, if you are new to Yu Gi Oh, you can pick up one of the automated games and play against an AI to see whats up. Even before that I recommend browsing decks online and picking one to start playing. After you fully understand your cards and what can you do with them you can go to building your own deck with respect to what everybody else plays if you want to be competitive. Good luck and have fun as always and if you see me on discord private message me for a game on DuelingBook.
