Lair of Darkness
Lilith is a Great card that Will tribute (in combinazione with the lair) your opponent Monster in order to get Normal trap card from the deck.
Ahrima is a Field spell searcher and once on the board it can help to search the lord of the heavenly prison, Arianna or Alice.
You can combo cards like ballista squad with the Field spell in order to tribute the opponent Monster and destroy one of his/her monster.
Loris (in the decklist is the Second copy of Alice) will give you recursion and draw power; trap Trick is 1 card 3 traps in grave/banish (1 banish 1 set and trap Trick) so it can work in synergy with Loris.
Labrynth
Arianna is really flexible because she can search any labrynth card with the lair and lilith you can start to control your opponent board. Example, you can Activate lair, lilith tribute for ballista, use ballista to tribute an opponent Monster and destroy one ohter Monster, Arianna Will lei you draw 1 and Special Summon one fiend.
Silver Castle is the boss Monster that Will give you protection and reuse trap from the grave, it Will work really well in combination with Lord.
