Help me with my Yu-Gi-Oh deck.?

instead of waboku, i'd put in negate attack. It does the same thing except it also ends the attack step, so if they have multiple monsters, you can stop them from attacking completely for that turn. Also if you can get one, use blast held by a tribute. Whenever a tribute monster attacks you, it automatically destroys all faceup attack position monsters on their field and does 1000 damage automatically. its a nice card
