"Mirror Wall":

Yu-Gi-Oh![edit]

This card does not have a Maintenance Cost and in the first two seasons, it also negated the attacks of the monsters it affected.

In episode 29, Mai uses this card during her Duel against Yami Yugi. When "Gaia The Fierce Knight" attacks Mai's "Harpie Lady", Mai activates this card to negate the attack and halve the ATK of "Gaia the Fierce Knight". On Yugi's next turn, "Summoned Skull" attacks "Harpie Lady", but Yugi forgot at that point that this card was a Continuous Trap Card. As a result, this card's effect negated the attack and halved the ATK of "Summoned Skull". Later Mai activates "Shadow of Eyes" to switch Yugi's "Dark Magician" to Attack Position and force it to attack "Harpie Lady". This card then negates the attack and halves the ATK of "Dark Magician". In the next episode, Yugi activates the effect of "Catapult Turtle" to Tribute "Harpie's Pet Dragon" (who Yugi took control of via "Brain Control") and destroy this card as well as inflict damage to Mai equal to half the ATK of "Harpie's Pet Dragon".

In episode 44, Mai uses this card during her Duel against Joey Wheeler in the coliseum. When "Flame Swordsman" attacks "Harpie Lady", Mai activates this card to negate the attack and halve the ATK of "Flame Swordsman". This card remained on the field until the Duel got canceled.

In episode 80, Mai sets this card during her Duel against Jean-Claude Magnum, but does not activate it. This card remained on the field until the Duel was over.
In episode 90, Mai uses this card during her Duel against Yami Marik. When Marik's "Masked Beast Des Gardius" attacks Mai's "Dunames Dark Witch", Mai activates this card to halve the ATK of "Des Gardius". "Dunames Dark Witch" then destroys "Des Gardius", but this allows Marik to activate "The Mask of Remnants" which equips onto "Dunames Dark Witch" and switches control of it to Yami Marik. Marik then activates "Remove Trap" to destroy this card.

In episode 102, this card can be seen when Téa Gardner was building her Virtual World Deck for her Duel against Crump.
In episode 106, this card can be seen when Duke Devlin, Tristan Taylor, and Serenity Wheeler were building their Virtual World Decks for their Duel against Nezbitt.

In episode 152, this card appears in a flashback that Mai Valentine has which relates to her many victories but feeling no joy from it. Mai uses this card during her Duel against an unknown opponent. When "Tri-Horned Dragon" attacks Mai's "Cyber Harpie", Mai activates this card to halve the ATK of "Tri-Horned Dragon". The opponent then activates "Rush Recklessly" to increase the ATK of "Tri-Horned Dragon" by 700, but Mai activates "Fairy's Hand Mirror" to change the target of "Rush Recklessly" to "Cyber Harpie Lady", increasing its ATK by 700. "Cyber Harpie Lady" then destroys "Tri-Horned Dragon", winning Mai the duel.
In episode 173, this card was shown in Mai's hand during Duel against Joey Wheeler. It drops from her hand right when she rushes over to Joey who had lost the Duel due to exhaustion.

In the non-canon duel YCS Providence 2012 Special: Mai, Joey and Yugi vs. Pegasus and Bakura, Mai uses this card against Pegasus. When Pegasus' "Harpie's Pet Dragon" attacks Mai's "Harpie Lady", Mai activates this card, halving "Harpie's Pet Dragon's" ATK and allowing "Harpie Lady" to destroy it by battle. The same turn, Pegasus attacks "Harpie Lady" again with "Relinquished" (whose ATK was 1500 due to being equipped with "Amazoness Chain Master" with its own effect). "Relinquished" becomes affected by "Mirror Wall", although it neither is destroyed by battle nor takes any battle damage due to its own effect.
In the non-canon duel World Championship 2013 Special: Mai vs. Yugi. Mai activates this card when Yugi's "Dark Magician" attacks Mai's "Harpie Channeler". However, as "Dark Magician's" ATK was 3200 due to being equipped with "Magic Formula", it was still able to destroy "Harpie Channeler". The ATK drop "Dark Magician" suffers from this card forces Yugi to use "Magical Hats" to protect "Dark Magician" from the attacks of Mai's "Harpie's Pet Dragon" and "Cyber Harpie Lady" the next turn. The following turn, Yugi destroys "Mirror Wall" with "Mystical Space Typhoon".
