Blazing Mirror Force destroys all of your opponent's Attack Position monsters, just like the original, but adds a very important and potentially game-ending effect. You must take damage equal to the half of the combined original ATK points of those destroyed monsters. The best part about this, however, is that you inflict the same amount of damage to your opponent. Used strategically, not only can this turn the tables on your opponent, destroying their attack force, but it can put their own life points to a point where either you can finish them on your next turn, or even right then.
Jason Imasogie included 2 copies of Blazing Mirror Force in his 1st place Regional Winning Burning Abyss deck in Birmingham, England. It marks the first time that this card has been a part of a major tournament winning deck. Burning Abyss is a strong archetype and it's surely not the last time Blazing Mirror Force will be included in this type of deck. Unlike the original Mirror Force, however, the timing of unleashing this trap is critical. Nevertheless, having such game-ending potential is what should make a Secret Rare Trap Card, and the designers of Yu-Gi-Oh definitely got this card right.
