Personally, I think Going Second Sky Striker is better than going first, I just haven't had time to post up a really good build until now! This build focuses on breaking your opponent's board and then setting up so they can't recover the next turn. One of the most powerful assets in the deck is
Mystic Mine. Most decks can't out this card and resolving this card going second most of the time means your opponent loses instantly since a lot of people don't main outs to Mystic Mine. Another card that is really good in this deck that I liked in testing is
Cynet Universe because it allows you to recycle your Kagari easily, especially since the deck is playing
Pot of Desires and you could possibly banish Hercules Base. I know a lot of people aren't playing 2 Eagle Booster but I like it because going second a lot of the time you need to resolve Kagari or Hayate, and if they try to stop your Kagari or Hayate then you can chain Eagle Booster. It's a card you sometimes want to see in your going second opening hand but not multiples of. The important outs to big combo decks like Thunder Dragon and Pendulums are in the side deck because we need to have a well rounded main deck since not everyone plays Thunder or Pendulums. In order to resolve Mine against combo decks you need to bait out their negates first with cards like Widow Anchor and then use Mine so they can't negate it. When Mine is in play, you can just keep passing until you can kill your opponent with
Borrelsword Dragon or by taking their monsters with Widow Anchor and attacking for game. I hope you guys like this deck!
