Vampire Nightlord

You can Special Summon this card (From your hand) by banishing 2 DARK monsters from your Deck or Graveyard. When this card inflicts 800 or more Damage to your opponent: Send 1 DARK monster from your Deck to the Graveyard.

Too easy to get out considering this would be in a Deck with a lot of DARK monsters to begin with. What were you thinking when you made it banish 2 DARK monsters from the Deck to Summon this? That's a simple 2400 ATK beater right there. The second effect is a Foolish Burial like card, yet this needs 800 damage to happen through this card. That may be a bit too simple to accomplish, though it does need to get an attack through. May be slow, but a bit too powerful imo. You need to rethink this card a bit, and I suggest you start by getting rid of the Deck portion in the Summoning condition.

I don't really like cards that use the Graveyard as a sort of extra deck, and this is one of them. In a Dark-monster heavy deck this card wouldn't be really hard to get out for a 2400 ATK wall of meat. It's slow though, but still needs to be nerfed. Maybe you could banish cards from your hand and you only need one, or you could simply just lower this cards attack and give it a better effect than a Foolish Burial on legs. All in all; 4.5/10
