NekroMatika

A deck of pure extra deck hate with tons of flexibility!

Very focused on using the extra deck as a tool box and extenders for both archetypes to send out powerful rituals that heaviliy restricts you opponent and can deal heafty damage. 

The main aim in the deck is to end with atleast a unicore and Alba zoa on the field, but follow up is very easy depending on the cards you get. 

Dogmatika is easiliy searchable and can lead to Fluer in hand and Nexus ready for a non target clear up. Alba Zoa gives extra protection to your Dogmatika monsters and can bounce your opponents extra deck monsters on the field or (especially if going first) rip half your opponents extra deck and/or part of their hand. 

On the Nekroz side, its mainly to get Unicore on the feild and negate all face up extra deck monsters on the field. The engine is also great for extending and if your in a tight pinch or want extra security you can add Valk which negates an attack and ends the battle phase. 

Theres extra consistancy with Preperation of Rites and Iblee serves as extra hassle for your opponent, preventing them to summon unless they use Iblee which can be placed on your opponents field using Lingkuribo - whos effect is unnaffected by Unicore as it send itself to grave for cost.

Ultimate slayer is a great side option as it allows you to have better use of your extra deck as a tool box.
