This a relatively easy deck to pilot, as long as you stay aware of the Fiend Lock after using the revive effect of the Evil Twin, and make sure to not lock your own monsters out of effects because of Knightmare Gryphon. You generally want to make Heatsoul + Conflict with Evil Twin Kiskil on the field and Lilla in the grave for your opponents turn. This often involves reviving Kisikil on your turn for a draw, and then linking the two into another Kisikil. If you have access to Challenge, you can make Knightmare Gryphon to floodgate your opponent or Unchained Abomination for more disruption, while still being able to revive the Twins on your opponents turn. Accesscode helps end games, and Saros Eresh Kurnugias can link off a hard to get rid of monster, as well as having some solid protection and negation.
This deck is also a work in progress, and I have various versions with different ratios or cards, such as Cynet Regression instead of Conflict, which does not rely on a Code Talker being on the field and doubles down on the "pop-and-draw" aspect of the Twins. One with 3 Code Generator and 1 Sea Archiver as a secondary target, for after Dotscaper has been expended, and one without Lilla Treat, because she wasn't revealed yet.
The deck has a pretty low ceiling, but I find it quite enjoyable. And if you have any questions regarding it, please ask, as my descriptions tend to be pretty basic.
