When this card is activated: You can send 1 Level 5 or higher Zombie monster from your Deck to the GY. You can only use each of the following effects of "Delta of Invitation" once per turn. If a Zombie monster is on the field: You can Special Summon 1 "Delta Token" (Zombie/DARK/Level 5/ATK 0/DEF 0).
