Just Numeron , it works , it OTKs , I use it a lot , it passes the test of time , you can expand upon it , but it works fine as it is , I think it is self explanatory how to use it , try to have a way to use Numeron network always , I advise to have atleast one Numeron Calling in your hand if you can , because even if your opponent negates Numeron Network, you can use it to recover , it can beat Dragoon that way , and other effects similar to that, I love that deck , I love it so much I created irl , I played a lot of troll OTK decks and gimmicky stuff , this is the one I think I had the most fun with
