First decks were unironically the kaiba and Yugi decks (then Joey and so on.) Mainly played with family and friends but I started going to meets and tourneys when I got the Zombie madness deck modified with some key cards for utility (Breaker, IFL, Jinzo, tsuku/BoM ect) Ultimately the goal was to work up to a chaos deck like my cousin. By the time I could afford it though all of the major cards were banned lmao
