Orcust build utilzing a small Rokket engine instead of the classical Scrap engine to enable Synchro 8 plays, making either Chaos Ruler, the chaotic magical dragon or Borreload-Savage Dragon.
Chaos Ruler is used to mill Orcust monsters into the GY to enable the Orcust engine very consistently when paired with Girsu, the Orcust Mekk-Knight and the Dark Warrior package as Combostarters.
Girsu + Quick Launch is VFD + Savage.
