Notes & Combos
The idea for this deck was for the main and extra decks to run zero LIGHT or DARK monsters to avoid enabling Bystials from opponents.
Eventually I decided to add 3 copies of Imesty. Although this is a DARK monster, it's effect of fetching King's Sarcophagus makes it worth including - if you're going first and you have no monsters, then the opposing Bystials in hand will not be active anyway.
Black Rose Dragon can be summoned using the level 3 tuners plus Planet Pathfinder. Ruddy Rose Dragon, and any of the Level 10 Synchros, can be summoned using any level 7 monster and a level 3 tuner.
Gameplay is pretty self-explanatory, just aiming to win using the effects of the Kashtira / Horus / Millennium engines and the extra deck monsters that can be easily summoned.
Nothing special, just some powerful and grindy effects.
