Rulings
- Mirage Knight cannot be Normal Summoned or Set, and cannot be Special Summoned EXCEPT by the effect of Dark Flare Knight. So Mirage Knight cannot be Special Summoned with Monster Reborn, etc., even if Special Summoned properly first.
- Mirage Knight can be Special Summoned by Dark Flare Knight's effect even if Skill Drain is active, because Dark Flare Knight's effect activates in the GY. However, Mirage Knight's effects are negated by Skill Drain.
- When a Mirage Knight that was involved in battle is flipped face-down, it is not removed during the End Phase.
- When a Mirage Knight that was involved in battle is removed from play with Interdimensional Matter Transporter or Dimensionhole, it is not removed from play during the End Phase by its own effect.
