Gundam Lfrith Thorn [R+]

Card Effect

(When this Unit's attack destroys an enemy Unit, deal the specified amount of damage to the first card in that opponent's shield area.) During your turn, when you play and activate a (Dawn of Fold) Command card using an EX Resource, you may pair that card from your trash with one of your Units with "Gundam Lfrith" in its card name.
