For me, it needs 3 of these!!
A few words about the deck, all Traptrix monsters are unaffected by Trap Hole cards, the XYZ monsters have good effects like banishing one card from your graveyard and destroying one monster your opponent controls (if I remember correctly), and the Link monsters help a lot in keeping your field refreshed with traps and Traptrix monsters! It just definitely requires attention on how one manages their rounds so as not to end up with nothing but Ash Blossom.

This structure deck is the best one currently available. If you get three, you can go to locals and defeat many people
