Less consistency due to the increased card pool. (Oh, boy, you can really feel the difference between 44 and 49 cards!)
Stronger and more reliable economy - this deck is using the standard ": 1 " action waaay less!
Even more glaciery build! The ICE are slightly stringer, slightly more expensive and there are slightly more ICE per card in total. Seriously, this deck can build a huge ICE block on the playfield in no time. The chance of randomly drawing 3 cards and getting no ICE is 18.66% - helloooo ABT!
How to get 4 per turn
Feed the runner an early Mandatory Upgrades by leaving it in HQ undefended or installing it naked.
Try to score out an early Mandatory Upgrades behind a cheap ETR ICE if the runner didn't catch your bait.
If you manage to score it out, congratulations, you now have 4 per turn for the remainder of the game. Your chances of winning just have drastically increased.
If you can't score it, well, don't worry. It's actually not in the deck to be scored, but to be stolen.
If the runner has a Mandatory Upgrades in his score area, use Media Blitz to copy it. Now you have 4 until the runner scores something. Make use of it while you have it!
Use Gila Hands Arcology, the poor man's Melange, to gain 3 and then install a card, triggering your ID.
Defend your HQ (if there are agendas in there), your R&D and a single remote by laying out some ICE.
If you get agenda flooded, try to use Jackson Howard, if not, try to use up your cards in HQ. When you're low on cards, use your remote to score normally or use Melange normally. It's riskier this way, but still possible. A layer of three cheap ICE can work wonders.
The 3/2 agendas are meant to be scored for points only. But that doesn't mean you shouldn't use them when there's a good opportunity. Jackson Howard can save you against a complete backfire of Accelerated Beta Test and Project Vitruvius can be used as a superior version of Jackson to bring back key cards right when you need them.
Cycle the Mandatory Upgrades. You want one copy to be stolen and the rest to be sitting in R&D or (only if you've got Jackson out!) Archives.
When everything goes wrong and you're with the back against the wall, use Media Blitz to copy Gila Hands Arcology. It's still better than having 3 Media Blitz in hand and click for creds, just because the runner stole the wrong agendas.
