A ruling came up at my local gaming event this week so I've had a long search around now and I can't find an official ruling on this. Also the rulings people are giving (including on this site) are always different and contradict each other.
What I'm wondering is if a monster is equipped by an equip card and then they are Forbidden Lanced does it fall off?
For example if I had an Inzektor Dragonfly on the field which was equipped by an Inzektor Sword and an Inzektor Giga-Mantis (equipped by Giga-Mantis effect) and I Forbidden Lanced the Dragonfly would the equip cards both stay?
Could you also Play an Inzektor Sword or Giga-Mantis on a Dragonfly if they have already been targeted by Forbidden Lance.
