Immortality (Dark Snake): If this Spirit Card is in your Trash, you can summon it to the Field when one of your Spirits in the Dark Snake family is destroyed.
[LV1][LV2][LV3] (When Summoned) If this spirit is summoned using Immortality, choose a spirit with a cost of 7 or higher from your trash, and summon it without paying the cost. However, that spirit cannot activate (When Summoned) effects.
