Ok, lads so this is the deck i used to climb from legend to KOG. Interesting thing is this is my first time I ever hit KOG and I've been playing for 2-3 months already. Also, this was the first time i hit legend too, but with an Ancient Gear deck (been stuck in platinum for ages). I believe this was due to the fact that I was (and still am) totally f2p, but first I hit a crazy win streak straight from plat 2 to legend 1, and then after being stuck in legend for several days i started farming Alexis, which surprisingly enough turned out to be easy even with a kaibaman deck after the nerf, and I had tons of blue keys so I managed to get all the cyber angel stuff I needed. I had 2 sonic birds and 1 senju since most of my gems were spent on U-rising and Neo-impact so I decided to give CA a try. I used Pegasus mindscan but more often than not i would brick, and couldn't deal with all the backrow which is pretty HEAVY in this meta, so I had a thought ... why not add a straight flush or maybe two? And this was the best decision EVER, completely wrecks AGs, GBs, DDburn, and many more decks. As for the strategy ... well you pretty much play the same as the usual CA deck, but a bit less agressive, and if your opponent is likely to set 3 backrow just pop that tasty tasty straight flush - in their end phase is best if you can. (Also, English is my 3rd language, so sorry for grammar mistakes)
