Rulings
- This card’s effect is an Ignition Effect that targets. Sending 1 card from your side of the field to the GY is a cost to active the effect.
- You cannot use a Monster Token for the cost because they are not sent to the GY.
- You can use this effect multiple times, but the same monster cannot be targeted with this effect twice.
- "While this card is face-up on the field" means "while this Elemental Hero Tempest is face-up on the field". Not while the selected monster is face-up on the field.
