As Mayakashi decks are want to do, "Hajun" and "Dakki" are the main starters to turbo out your synchros, allowing you to synchro-climb until you reach "Gashadokuro". Once there, since "Dakki" will have returned from the graveyard, you can use her and "Gashadokuro" to summon "Yuki-Ona, the Ice Mayakashi", so that when she's destroyed, "Gashadokuro" will come back as a veritable "Dragoon" for a turn. Additionally, while you are synchro-climbing, if it's in your hand, you can use "Deal with Dark Ruler" to summon "Berserk Dragon" from deck or hand to decimate your opponent's monsters, leaving them wide open for direct attacks.
