A beatdown deck relying on low-leveled but high attack monsters to deal damage, and defense cards to maintain field control. Most cards in this deck have effects that work well on their own, so almost anything you get in your starting hand will allow you to make plays.
Card Guard gains a Guard counter when he is summoned. This counter can be kept on Card Guard to increase his attack or can defend a card which receives it from Card Guard. You can also have a Card Guard give his counter to another Card Guard to further increase its attack and gain protection.
Everytime BOXer destroys an opponent's monster by battle he gains a counter, these counters can be used to prevent BOXer from getting destroyed.
"This counter can be kept on Card Guard to increase his attack and defend himself once or passed to another card on your field." Clearly this deck is done by amateurs who write more than playing the game, if you actually play Card Guard you would know the counter does not protect Card Guard itself. Trash deck btw.
