The dragonmaid archetype is one based off of (loosely) the anime Kobayashi's Dragon Maid, where the humanoid "maid" dragons have bigger dragon forms.
In practice, the deck is basically boneless dragon link with a slightly more control oriented and grind-game focused gameplan.
Featuring an omni-negate boss monster (Sheou), and various starters to gain access to your fusion spell and 30 million extenders, this deck is probably the main deck to make use of the Hieratic link monster.
The deck can make use of dragon link-esque guardragon combos, as well as various interruptions in the form of the hieratic link, and the trap Dragonmaid Tidying.
tl;dr dragon maid waifus gain advantage every turn because of their angry boss monster who turns into her normal self after saying no as well as going +2 every standby phase.
Pls R/F with suggestions to main/extra.
Side deck subject to change based on local metagame IRL but it's one I just made for online play.
