You can start with 1 Gozuki/Samurai Skull, then you send Vampire retainer or familiar to graveyard, send another retainer/familiar as a cost to summon a vampire from graveyard; that cost that was sent can be summoned again in the same way. Then you have already 3 monsters on field to E-Con take and if you have Vampire Kingdom on field you can use it to destroy a card with Vamp Grace. It's amazing!
