Can anyone tell me a good succesful yugioh deck of only magic and trap cards?
With only Spell and Trap cards, the only most successful deck is a Burn deck. Just keep having Hand Destruction to draw burn stuff and using stall cards such as Level Limit -Area B and Gravity Bind. Don’t really know there IS a successful deck with consisting of Spell and Trap cards, but I guess half a year ago, a Chain Burn deck was created of Spell and Trap cards was on the top SJC with only five monsters. See if you can go less than that amount of monsters. Good luck.
