Double Empen is a good combo extender, you can go turn 2 double Empen statue with the dream, offers a faster deck cycle, in the starting hand helps u play around negates in case you have the map and your Eglen gets negated, huge damage push, it allows you do go for more summons with winds, insane pressure impossible for decks to remove 2 Empens, in case one gets removed you have the second on board while getting back the first one that died, enables Stri to be used offensively, good for the mirror match and you don't auto lose in case it gets 'evenly matched'. The only downside is it can brick, but happens once every 20 games, while 1 Empen has far more downsides!

Nice, thank you for your kind words. Evenly is a meta-breaker and one of the best cards in the deck. Additionally, Gold Sarc is a decent option, but I don't think there's space in a 40 cards Floo deck for it, there are way better cards you can run!

My extra deck runs the best possible options in cards for this deck, they are not all necessary though. The important ones are ‘ Lyrilusc - Assembled Nightingale’, ‘Downerd Magician’, ‘ Divine Arsenal AA-ZEUS - Sky Thunder’ and ‘ Underworld Goddess of the Closed World’!

Depends on the matchups and on the board state. I personally always run 2x Pot of Extravagance, the card I replace for Crossout is Duster.
