Gravekeeper Master Duel Necro Control

With this deck, you really want to go first. If you can get Necrovalley on the field and hit your oppenent with a royal tribute on the 1st turn, they pretty much are screwed, depending on deck honestly. My rule of thumb is to always keep necrovalley on the field. Getting Hidden Temples on the field is also huge, to stop oppenent from special summoning in general, which shuts down many decks. Getting Supernatuaralist on the field is huge too, grabbing any gravekeeper card you need. Play the x3 Torrential and x3 Judgement to keep yourslef in the game if you don't get the right draw right off the bat. I love the Ash Blossom for when I don't get to go 1st, try to limit what's on the field. The only monster I really use from the extra deck is the Supernaturalist, but you can play around with that. I use high ATK monsters for Dogmatika.
