yu gi oh vampire deck YGOrganization Vampire Lord - Structure Deck:

The deck's landfall shenanigans can easily get out of hand, and WotC even included an infinite combo when making the deck (Yedora Grave Gardener + Sakura-Tribe Elder + Zimone)

My build oriented toward Aura-enchantress (partially as I was fresh off of Sigarda, and partially because Jeskai auras is kinda neat)

Fire Brotherhood of the Fire Fist - Swallow You can Special Summon this card (from your hand) by sending 3 face-up "Fire Formation" Spell/Trap Cards you control to the Graveyard

(1) If a face-up D/D/D and/or Dark Contract card(s) you control is destroyed while this card is face-up in your Extra Deck (even during the Damage Step): You can Special Summon this card, then you can destroy 1 card on the field
