Went undefeated at locals a few times and done well pretty much every other time.
Warior lady removes herself to keep totem dragon live
Double masked dragon into exploder dragon to (usually) force them to stop attacking or make them 1:1 with something at the end
Plague as the only tuner but being able to revive him and do it twice + keep him out of the grave for totem dragon.
Fiendish Chains deal with problems like Judgment Dragon, Archlord Kristya, until you can book of moon, lightning vortex, Brionac, etc, etc. Could clog the field but you will likely only have one out at a time and also have giant trunade to recycle them, or heavy storm to get rid of them later if needed. Also helps keep starlight road live if they heavy storm, etc. Ive found they dont really cause a problem though usually. Best to use on boss monsters (usually). Not ones that can easily be used as synchro material.
Chain Dissaperance in the side is really good against some decks like Dandywarrior. You can get rid of all of their quickdraws or dandylions and shut it down quickly.
Electric Virus is great against Lightsworn, Mirror Matches, and just a lot of decks since dragon synchros are so common in the format.
With Future Fusion I usually dump 2 Wyvern, 2 Darkness Metal, and Prime Material but obviously that depends on what else you already have.
