CARD ID: 44095762
STATUS TCG: Unlimited
Powered by yugioh.wikia.com
This card was the first card released that could only be activated in response to an attack.
Originally, this card also had an effect to negate attacks, being able to stop the attack of Total Defense Shogun and Elemental HERO Rampart Blaster. Its most recent errata states that it does not negate attacks; this is more than likely because of the fact that, while some monsters can attack from Defense Position, the monster triggering Mirror Force is more often than not in Attack Position (usually negating its attack by proxy).
As of yet, this is the only card to appear in every Yu-Gi-Oh! anime series.
This card has spawned many counterparts, often Type or Archetype specific or downgraded in effect, including the following:
Blackwing - Backlash
Blast Held by a Tribute
Blazing Mirror Force
Cell Explosion Virus
Dark Mirror Force
Drowning Mirror Force
Koa'ki Meiru Shield
Mirror Force Dragon
Quaking Mirror Force
Radiant Mirror Force
Rose Barrier Force
Shining Silver Force
Storming Mirror Force
Wall of Thorns

There can be multiple chains in the Battle Step before entering the Damage Step. Only the initial chain can directly respond to the attack, and only in this Chain can you activate cards such as "Mirror Force", "Sakuretsu Armor", and "Magic Cylinder" (Cards that can only be activated when your opponent's Monster declares an attack). Cards that do not have this restriction ("Book of Moon", "Compulsory Evacuation Device", "Waboku", etc) can still be activated in another Chain before entering the Damage Step.: Chains / Cadenas: battle phase timming: Attack response
If "Mirror Force" is activated while the effect of "Royal Decree" is applied on the field and "Mystical Space Typhoon" is chained to "Mirror Force" targeting "Royal Decree" then "Mirror Force" is Chain link 1 and "Mystical Space Typhoon" is Chain link 2. The Chain resolves backwards. "Mystical Space Typhoon" destroys "Royal Decree", "Mirror Forcethan resolves and destroys all Attack Position monsters the opponent controls. Since "Royal Decree" is no longer face-up when "Mirror Force" resolves, it will not negate the effect of "Mirror Force".: Royal Decree Vs. Mirror Force and MST
Battle Fader: "Battle Fader" has a Trigger effect and must be activated as soon as the Trigger condition occurs.
For example, Player A (the turn player) controls a face-up "Light and Darkness Dragon while Player B has a Set "Mirror Force" and "Battle Fader" in their hand. Player A declares an attack. Since "Battle Fader" has a "Trigger Effect" it must be activated directly to the Chain in respond to the attack as Chain Link 1. If Player B activates "Mirror Force" first then he will not be able to activate later "Battle Fader". So, "Battle Fader" will have to be Chain link 1. The effect of "Light and Darkness Dragon" will be Chain link 2. Player B may then activate "Mirror Force" as Chain link 3.: Battle Fader vs LADD vs Mirror Force: Legendary Six Samurai -Shi En vs Mirror Force vs Dim. Prison
Battle Fader: The effect of "Battle Fader" is activated during the Battle Step and not the Damage Step, therefore you will be able to activate the effect of "Royal Oppression" to negate the Special Summon of "Battle Fader".
"Battle Fader" has the same timing as cards like "Mirror Force", "Sakuretsu Armor", and "Magic Cylinder". This means you have one opportunity to activate it, the initial chain in direct response to the attack declaration. If you allow the current chain to resolve ("Battle Fader" > "Royal Oppression"), you will not be able to activate a 2nd copy of "Battle Fader".
Unlike the other cards listed above, "Battle Fader" has a Trigger Effect, so you would be unable to activate multiple copies of "Battle Fader" in response to the same attack declaration.: Royal Oppression Vs 2 Battle Faders
This card does not target.: Trap Card > Mirror Force
If a card like "Mirror Force" is activated in response to an attack, then "Negate Attack" can still be activated in chain. However, note that "Negate Attack" will resolve first, so cards like "Enchanted Javelin" or "Magical Arm Shield" will resolve without effect because the monster is no longer attacking. Cards like "Mirror Force" or "Widespread Ruin" which have the text, "Activate only when your opponent declares an attack." only have the attack declaration as activation conditions, so their effects will still be applied even if the attack is negated. If "Kunai with Chain" is activated and then a chained card negates the attack, then "Kunai with Chain" will still give +500 ATK, but the attacking monster will not be changed to Defense Position.: If "Magical Arm Shield" or "Enchanted Javelin" are activated in response to an attack, can "Negate Attack" be chained?
There is no attack declaration when battling by the effect of "Equip Shot" - it moves the game forward to Damage Calculation when resolving the effect. Card like "Mirror Force" and "Sakuretsu Armor" cannot be activated because of this.: When battling by the effect of "Equip Shot", can "Sakuretsu Armor" be activated?
You can activate "Morphtronic Forcefield" against "Mirror Force" if you control a face-up Attack Position "Morphtronic" monster.: Can "Morphtronic Barrier" be Chained to a card which does not target?
"Obelisk the Tormentor" can be destroyed by effects that do not target, such as "Judgment Dragon", "Lightning Vortex", "Mirror Force", etc.: Can a face-up "Obelisk the Tormentor" be destroyed by effects that do not target like "Lightning Vortex"?
If the effect of "Scrubbed Raid" is activated when a monster declares an attack, then the Battle Phase ends, so the attacking monster can no longer be treated as an "attacking monster".: If the effect of "Scrubbed Raid" is activated in Chain to the effect of "Sakuretsu Armor" or "Mirror Force", then is the monster destroyed?
If the effect of "Scrubbed Raid" is activated in Chain to an effect like "Sakuretsu Armor" or "Dimensional Prison", then the effect of "Sakuretsu Armor" is not applied, and the attacking monster remains on the field.
If the effect of "Scrubbed Raid" is activated in Chain to "Magic Cylinder", then the Battle Phase ends, so "Magic Cylinder" cannot negate the attack so the effect of inflicting damage equal to the monster's ATK is not applied.
The effect of "Mirror Force" only destroys all monsters in Attack Position, so all Attack Position monsters will still be destroyed even if the effect of "Scrubbed Raid" ends the Battle Phase.

The Six Samurai: You cannot destroy a “Six Samurai” monster to save more than one other “Six Samurai” monster at the same time. Example: You control “Yariza” in Defense Position and “Nisashi” and “Irou” in Attack Position. “Mirror Force” is activated when you attack with “Nisashi”. You can destroy “Yariza” to save “Nisashi”, or destroy “Yariza” to save “Irou”. You cannot destroy “Yariza” to save both “Nisashi” and “Irou” at the same time.
Six Samurai: A “Six Samurai” monster that is in the process of being destroyed cannot be destroyed to save another “Six Samurai” monster.

Tyrant Dragon: When you attack with "Tyrant Dragon" the opponent can activate "Mirror Force" and all your Attack Position monsters, including "Tyrant Dragon", will be destroyed. This is because "Mirror Force" does not target.
