Domain Dragonmaid Dragon Ruler Bystial LaDD

I do regret how this deck ended up as a slop pile, as the actual intent was a deck that could turbo out as many Maids and maid-adjacent cards as possible. I personally prefer to play the deck as such, only going all-out if I have no other choice.

Main Combo

1. Summon Chamber Dragonmaid

2. Search Dragonmaid Hospitality

3. Link Chamber Dragonmaid for Spirit With Eyes of Blue

4. Use Spirit's effect to add Mausoleum of White to hand

5. Activate Dragonmaid Hospitality, reviving Chamber and sending Cehrmba from deck to GY

6. Banish Chamber and Cehrmba to fusion summon Lady's Dragonmaid

7. Lady's Dragonmaid summons Parlor Dragonmaid

8. Parlor sends Dragonmaid Tidying from deck to GY

9. Play Mausoleum of White from step 4 and activate it, targeting any card and sending Blue-Eyes White Dragon to the GY

10. Send Spirit With Eyes of Blue to the GY, reviving the sent Blue-Eyes White Dragon

11. Overlay Blue-Eyes and Lady's to summon Dragluxion

12. Dragluxion adds Galaxy-Eyes Tachyon Primal to hand

13. Special summon Tachyon Primal using it's effect and add Galaxy Transmigration to hand

14. Use Dragluxion's effect to special summon Hope Harbinger Dragon Titanic Galaxy

15. Pass turn

16. On the opponent's turn (preferably standby phase, as most of the remaining steps take place there), banish Dragonmaid Tidying from your GY to revive Lady's Dragonmaid

17. On summon, Lady's Dragonmaid summons another Dragonmaid from deck (I prefer Kitchen, but it really doesn't matter)

18.If you searched Kitchen, she can add and discard whatever you want (I usually add either Lorpar or Nurse, depending on factors)

19. Lady's Dragonmaid effect activates to fusion summon Dragonmaid Sheou, shuffling Chamber and Cehrmba back to the deck/Deck Master Zone

20. Freestyle from here, you have 3 negates on board and plenty of other monsters to do what you need with

(Note: During the end phase, Lady's Dragonmaid is shuffled back into the Extra Deck as a result of being revived by Dragonmaid Tidying.)

Extended Combo

If you have a Light End Sublimation Dragon or Dark End Evaporation Dragon in hand, you follow the previous combo up until step 14, following with these next steps. For the record, though, you can cards such as Magical Contract Door or Reload to make this more consistent.

15. Banish the original Dark End Dragon from your GY to summon your End Dragon from hand

16. Banish Dragonmaid Tidying to revive Lady's Dragonmaid

17. Activate your End Dragon to fuse Lady's Dragonmaid with Parlor Dragonmaid to make Dragonmaid Sheou

18. Overlay your End Dragon with Tachyon Primal to make Galaxy-Eyes Tachyon Dragon

19. Use Tachyon Dragon as material for Galaxy-Eyes Dark Matter Dragon

20. Activate Dark Matter Dragon, sending 3 Dragon Rulers from deck to GY (I recommend Tidal, Redox, and Blaster)

21. Banish Tidal and Redox to summon your third Dragon Ruler

22. Tidal and Redox activate their search effects, adding Dragonmaid Ernus and Laundry Dragonmaid

(Note: Laundry can be replaced by Kitchen in this combo if more optimal. Adjust the steps accordingly if you choose to deviate.)

23. Discard Ernus to special summon Laundry Dragonmaid

24. Use Laundry and your Dragon Ruler to link summon Hieratic Seal of the Heavenly Spheres

25. On your opponent's standby phase, Dragonmaid Sheou revives Lady's Dragonmaid

26. Do not use Lady's effect to summon from deck, as the remaining monster zone must be left empty for Spheres' effect

27. Use Lady's other effect, shuffling her and Dark End Dragon to the extra deck to summon Light And Darkness Dragonlord

Your end board should consist of Hope Harbinger, Dark Matter, Sheou, Dragonlord, Heavenly Spheres, and a facedown Tachyon Transmigration. Dragonlord's negate effect will respond to everything, so keep that in mind.

28. Once Dragonlord is unable to negate anything anymore, you may activate Spheres to bounce an opponent's card and summon Bystial Baldrake

29. Baldrake may tribute the used up Dragonlord as a way of further disrupting the opponent.

30. Drink some water, you've earned it.
