Going second Lair of Darkness

The main goal for this deck is to go second so you can activate Nibiru, The Primal Being or use the super poly to summon Predaplant Triphyoverutum or Predaplant Dragostella which allows you to control the board.

There are still some classic combo with Ahrima, The Wicked  Warden and Darkest Diabolos, Lord of The Lair. The Danger! monster are here to help get rid of some annoying monsters and Spells/Traps. Or you can special summon them and make a rank 8 XYZ with the classic Galaxy-eyes package.

To protect your field spell, you can summon Beat cop from The Underworld using link spider and another token.

The card advantage is quite hard to maintain sometimes so two copies of Recurring Nightmare can be useful.

If you don't need Nibiru, you can still discard him to the Graveyard (there are plenty of card effect for that in the deck) since it's a light Attribute target for Chaos Dragon Levianeer.

I'm playing one copy of Fantastic Striborg because since it bounce to your hand the tributed mosnter. You cans for exemple send back to your hand Danger! Bigfoot!, summon Striborg. Then discard Bigfoot to bounce back to your opponant hand one or two cards on his field, then destroy a third with bigfoot's effect.

In the future, I'm planning to replace striborg with Archnemesis Eschatos (available in eternity code ) since it  can be searched with the melody of awakening Dragon and have  a quite interesting effect in my opinion.

The only traps I'm playing are the Eradicator Epidemic Virus since it can be quite effective against lot of decks like Shadoll, ... and if you tribute your own monster you'll be able to summon Diabolos.  I wouldn't recommend playing others virus card because there are too specific.

The side deck is built in order to go first with a more classic play style, using Lilith, Lady of Lament, Artifact Sanctum, ...
