What deck should I use in a yugioh tounament?

Use your rock deck if you have Magic Jammer or Counter Trap Cards that negate activations of Spell Cards because they can just use Smashing Ground to destroy your Rock-Type monsters.For your Spellcaster deck use Magician of Faith. A Burn deck is really good but its direct damage is too slow. There is no such thing as a Chuck Morris Deck, so definitely not. It doesn't exist. A Dragon deck is really powerful if you have Blue-Eyes Ultimate Dragon, Dragon Master Knight, B. Skull Dragon, Red Eyes B. Dragon and Dragon's Rage would be the best Dragon monsters or Dragon support cards. Equip deck is not so good if you don't have warriors. Removal from play deck is your second best deck. Finally, I've decided that you should use your Synchro deck. Good Luck at the tournament.
