Idk if I wanna try 5ds. Can I be old school and use old school decks?
There are no rule that forbids it. Just follow the official forbidden list, and any deck can be made.
My one and only deck consist of OLD cards from the 1st Gen Yugioh, and it still works like a charm. (combined with newer ones for effectiveness and efficiency)
I'm literally facing off with friends that uses new generation cards, and I can still give them a run for their money occasionally.
