Due to the types of those two archetypes [Fairy] they combo surprisingly well.
There are alot of combos between these two archetypes. More than I could represent here.
[Darklord combo]
The best way and the main way for the deck to get big beatsticks on the Board. The main way to get Darklords on the Board is to find a way to get them to the grave. This is extremly simple due to there effects. Everything you need for one combo is Ixchel and one Darklord card. (preferebly Superbia) By discarding Ixchel and another Darklord card you'll be able to draw 2 cards. With Darklord Contact or Banishment of the Darklords you will be able to summon those two Cards back on the Field to either use them for a link summon or a fusion summon. Nearly every Darklord has a second effect you can pay 1000 lp to activate a darklord card from your graveyard. Nearly every Darklord card works like Ixchel and therefor its extremly easy to have 4 or more monsters on the Field at once.
[Despia combo]
The Despia Cards work as a support for the Darlord cards. With Aluber you will be able to get the Despia Fusion spell with which you will be able to summon the Darklord or despia Fusion monsters.
[Fusion Monsters]
The First Darklord has a special effect that triggers when you summon him with darlord Morningstar as Material. You will be able to destroy every card your oponnent controls. And your opponnent can't really counter this effect because The First Darlord makes it so that Fairy monsters can't be targeted for effects.
