Van'Dalgyon, the Darkness Metal Lord

Sideboard (and deck as a whole) is a WIP

- Looking to get value from Red-Eyes Darkness Metal Dragon with supporting Traps,

- Discard a powerful Dragon card with Divine Wrath, Special Van'Dalgyon and bring a Dragon back alongside it for huge tempo.

- Future Fusion REDMD + Wyvern to GY to bring it out right away (potentially 2), then use its effect to SS Van'Dalgyon for another 2800 body.

- Otherwise, Yamata can't be Special Summoned but can be Tribute Summoned with Totem Dragon for a potential Draw 5, especially when you have the Counter Traps to allow it to resolve/attack.

Masked Dragon can get Totem (or Magna) into the GY pretty easily (so Totem can SS itself or Magna can be brought back with REDMD), or just to thin the deck (bring another copy out then go into Exploder Dragon).

Van'Dalgyon plus Magna Dragon can Synchro to make Trident Dragon for a big late game blow out.

Koa'ki Meiru is a powerful anti-meta card to bring out, especially after getting a board set up, but you have to be a little careful as it turns off REDMD/Wyverns/Van's ability to SS anything Light/Dark (still leaves you with a few options however).

Magna Dragon can be used over and over with REDMD, though have to be mindful of any Non-Dragon Synchro's you summon as they can turn off Totem Dragon, but I feel by that point your probably going to be in a good position anyway.
