Your goal is to end with a DPE + Babel minimum on board + Dingirsu in the GY.
Standard full combo endboard is DPE + Babel + set Scythe + PUNK trap.
Opening E-Tele is full combo.
Opening Girsu or Scrap Recycler is standard board.
Opening E-Tele+ MKPurple/Girsu/Recycler is full combo that plays through Nibiru.
For full combo (E-Tele+MKPurple/Girsu/Recycler+3 random cards):
- E-Tele -> PUNK Ze-Amin -> search Foxy Tune
- Foxy Tune ditches itself and a card (ideally Orcust Knightmare/World Wand/Cymbal Skeleton) -> Madame Spider -> search PUNK trap
- Spider + Amin = Crystron Halq->Halq summons Orcust Brass Bombard
- If MKPurple in hand
- Summon MKPurple under Halq after setting PUNK trap in same column
- (we're trying to avoid normal summoning to force out Nibiru)
- THIS IS OUR FIFTH SUMMON. If we do not have MKPurple, Galatea is our fifth summon.
- If Girsu or Recycler in hand
- Hold in hand on proceed to:
- Halq + Bombard = Galatea (Current board is set PUNK trap & Galatea, maybe MKPurple)
- Normal Summon Girsu/Recycler -> send Orcust Knightmare/World Wand/Cymbal Skeleton (in that priority order)
- Girsu/Recycler+Galatea = Artifact Dagda (if you have a way to trigger Dagda, one of the following)
- A spell (E-Tele/Babel/Foolish Burial/Fusion Destiny)
- Extender (E-Tele/Psychic Wheelder[summon with the PUNKs]/Orcust to special with Bombard)
- Assuming you have an extender for this example
- Knightmare(GY) -> World Wand to GY
- World Wand to GY summon Knightmare(banished)
- Summon [extender]
- Knightmare + [extender] = Galatea(ED2)
- Galatea -> shuffle back dark machine & get Babel
- Chain Dagda -> set Scythe
- Galatea = Dingirsu overlay
- Dingirsu + Dagda = Predaplant Verte
- Verte -> Fusion Destiny (& materials)
- End board:
- FIELD: Babel, DPE, Verte, set Scythe, PUNK trap
- 2 random cards still in hand
If you didn't have a way to activate Dagda, you can make I:P instead to Unicorn on their turn.
Compared to current common Orcust endboards, this isn't much fancier aside from having one more monster negate (PUNK trap) and Scythe lock possibly. The benefit of this build is that the Halq combo attracts the Ash, Imperm, and Nib before you have to Normal Summon (assuming you open E-Tele).
Common 40-card Orcust builds play 6 starters to get to Galatea (Girsu, Recycler)
This 51-card build plays 12 starters (Girsu, Recycler, E-Tele, Ze Amin) + letting you play around interruptions.
