Notes & Combos
Here's the ABC Cyber Dragon Deck I used to get from plat to diamond. I'm not even going to lie it took quite a while after making it to reach diamond but it was a ton of fun. Even though the ABC strategy also uses a normal summon which coincides with core, it worked out better than I thought it would. The deck can go 1st or 2nd which is a nice change of pace from the normal go 2nd cyber dragon. Can set-up powerful boards but also has plenty of board-breaking potential. The downside is plenty of bricks (orbital, drawhand, driver, dasher, LS if you chose 1st).
Going 1st you want to prioritize the ABC route so drawing into Union Hanger or Unauthorized Reactivation is quite important. Union Hanger alone is a 1 card combo that can finish with your choice of DPE or Cyber Dragon Infinity + ABC Dragon Buster (AND ALL 3 IF YOU ALSO HAVE A GALAXY SOLDIER IN HAND). Then on your opponents turn ideally you want to utilize Dragon Busters effect first to quick-effect banish and also jump off the field to bring out all 3 pieces and set up another Dragon Buster next turn. If you made I.P. turn 1 then it also allows u to use the pieces to go into Apollousa aswell. Going 2nd its ideal to use the Cyber Dragon stuff to OTK, and that can be assured by baiting negates with the Union Hanger or Lightning Storm.
Obviously a VERY rogue strategy but a very fun time nonetheless.
