Vampire Fiend

While in field, this monster name becomes "Vampire Lord". If you control 2 or more Zombie monster, including at least 1 Vampire monster, you can Special Summon this monster (from your hand or GY), but banish it when it leaves the field. [1/turn], if you gain LP by another card effect, you can target 1 monster your opponent controls with ATK lower than the ammount of LP gained and 1 Vampire monster in your GY or banished with ATK equal than or higher than the ATK of the first target; destroy the first target, Special Summon the second target and gain 1000 LP. In the end of Battle Phase where this monster destroyed monster by battle and sent them to the GY, you can Special Summon as many of these monsters as possible to your field. Each effect of cards with this name can only be used [1/turn].
