Card 6/4

Holy Barrier- Mirror Force/Mirror Force

Normal Trap

When your opponent attacks, you can activate this card.  Destroy all face-up monsters on your opponents field that are in attack position.

Pro

-Has put fear deep into the minds of any player for years

-Destroys all monsters on your opponents field that are about to destroy your lifepoints

-Great for literally clearing your opponents monster field.

Con

-Since it is so widely known, most people use up to 5 anti-magic/trap cards in their deck. 

-Ive yet to see any truly experienced players who runs head first into a Mirror Force and not have a large back-up.

A revolutionary card that changed the way people played forever.  When Android Psycho Shocker/Jinzo is in almost every other deck, yet you still use this card, that shows power.

This card is officially a legendary power-house. 

It perfects the ability to stop attacks, protect lifepoints, and possibly clear a monster field for direct attacks.

The only problem that I can see with this trap is the chain factor.

This card cannot be chained to anything other then an attack, and that could mean that you wont even get to activate this card.

Still, fear goes a long way when your opponent spends most of the duel waiting for that one Mirror Force to show itself so he/she can relax.

9/10- The staple card of monster destruction.  Negate Attack is useless once compared to this card, and it is the god card compared to Reactive Armor/Sakuretsu Armor.  The power may have weakened quite abit since the past, but what trap hasn't?
