Vampire Herr

(Quick effect) During the turn that a Zombie Monster was Special Summon from the GY to the field, you can Special Summon this monster from your hand. If a "Vampire" monster with another name you control would be destroyed by battle or card effect, while this card is in your hand, you can discard this card, instead of destroying these Vampire monsters. If a Vampire monster you control with another name inflicts battle damage to your opponent, you can gain 500 LP. In the end of each Battle Phase where this monster destroyed monsters by battle, you can Special Summon to your field as many of these monsters as possible, as zombies monsters.
