I like the write up. Gabe is in contention with one other deck for store champs for me, so this read hits close to home. It sounded like your deck was going to be just like mine before I scrolled down to it, and it ended up being very close.
I 100% agree that quality time is worth looking at...as I personally slot three of them. The flow of Gabe is such that you can play out the cards in your hand in rapid succession, so burst draw is fundamental to the ID in my mind. Static draw like Masnori looks good to hasten the draw instead...but as mentioned it kills tag-me fast.
I wash back and forth between 1 CC and 2 parasites and 3 parasites my self, as I run Rex and passport only, and reviving a Rex happens once in a blue moon for me.
For the big reveal, I do not run datasuckers. Power shutdown is a big issue for the build, as you're open to it pretty heavily. Your build avoids this by not making it 100% necessary (datasucker). Also with OnC coming up, I can easily see corps slotting the cyberdex duo (or either), so I'm less interested in datasuckers for the influence. Your breaker suite takes an effective stance on not needing suckers, and that is sweet.
My major concern is the strict lack of multiaccess...no chance of a lock seems very tough in the current meta. I know stuff like business show and fast track already kill that idea, but at least those can be answered.
Thanks for putting the time into the write up Xenasis.
