Rulings
- If your opponent chains "Enemy Controller" to the activation of the Flip Effect of a "Charmer", and takes control of the "Charmer", the Flip Effect disappears.
- If you take control of the opponent’s monster with a "Charmer" and the opponent takes control back with "Change of Heart", control still reverts to you after the effect of "Change of Heart" expires (even though it wasn’t your monster originally).
- If your opponent takes control of your monster with "Snatch Steal", and you activate the Flip Effect of a "Charmer" to take it back, you keep control while the "Charmer" is face-up on the field.
- If "Book of Moon" is chained to the Flip Effect of a "Charmer" to flip the target monster face-down, the effect of the "Charmer" disappears.
- If a "Charmer" is removed from play with "Interdimensional Matter Transporter", its effect is not re-applied when it’s back on the field.
- If "DNA Transplant" changes a monster’s Attribute so that it can be taken by a "Charmer", and then "DNA Transplant" is destroyed so that the monster’s Attribute no longer corresponds to the effect of the "Charmer", the controller of the "Charmer" loses control of the monster.
