Traps(4)

Demise: Clears the field, prepares the OTK. Can be used for Trade-In if you need to.

Masked Beast: Searchable, can be used for Trade-In, can be summoned as a last effort play, fuses to make a powerful Dark Gaia.

Beta/Gama: Normal Rock monsters. The rocks are less searchable than the fiends, Advanced Ritual Art + these solve that problem. Obviously drawing three in the opening hand would be bad but all decks can have bad draws. Annoyed at the lack of A)Rock Ritual Monsters and B)Normal 2500+ Atk 8 star rock　monsters.

Manju/Senju/Sonic: Search out he right cards at the right time. A good opening move often involves Manju/Senju searching for The Masked Beast to act as Trade-In fodder.

Trade-In: Ditches the monsters I can't summon and lets me draw cards. From the graveyard they can be Dark Called.

HS/GT: Clears the backrow to ensure a successful Demise hit.

ARA: Searches for Rock Monsters(This is needed because there are no ways of adding Valkyrion to your hand that I am aware of and no Rock Ritual monster exists IIRC). Summons Demise for little commitment of resources.

Contract: Works for both Demise and The Masked Beast in a pinch.

Monster Reborn: Just great for extra damage, another Ritual offering, whatever the opponent has handy...

Torrential: Stall in destruction form.

Gravity Bind: More stall.

Pretty simple don't you think? Its a fast paced OTK deck that could do very well if used properly.　 Cards that I would suggest putting in if you have the them: 2-3xAllure of Darkness+1x Senju, drop the Messengers and a Sonic Bird. Adds a little more speed to an already fast deck. Just make sure there is a powerful fiend in hand/in the graveyard for when you activate Dark Calling.
