I do want to preface first and say I'm sorry if I'm coming across as a know-it-all or like I'm personally insulting the deck. I'm not. Just putting forth my honest opinions and reads on cards to try and get down to the meat: How Do We Make Sunny (More) Awesome?
I hadn't read the original write-up. I read it just now, and honestly it looks like he discounted 2inf options for draw really quickly (ProCo) and forced an OCA build. I've seen @higgs_bozo around, and we cool. Mmm, trying to make Cybernetics Division work... Heh. Anyway. I do agree with the analysis of the 1-inf options. Drug Dealer isn't where Sunny wants to be I think, because as he said, unlike some decks, Sunny needs cards and money. QT has the same sort of issue, where the cost of the card is real, and also runs into the redundancy issue, where Sunny needs most, if not all, of her cards to function, and can't usually afford to pitch extras. Out of the 1-inf options, OCA is the best to build around, with QT being second-place I feel.
I like the argument for 2 Suppliers. It also makes more sense with Faust. I still prefer Hostages instead because no matter when I draw a Hostage, it's always a useful card. 3 Hostage + 1 Supplier also gives the maximum chance I see Supplier on turn 1, while only spending 8 influence. The damage problem is real. Tags... If you get tagged and have a Supplier, you're probably already hosed.
I do not in fact use Daily Casts, because it's slow econ. The same reason is behind not using Kati. Daily Casts costs a click, and then makes you 1cr in two turns, maxing out at making 5 money in 4 turns, or 7 money in 5 turns if you put it on a Supplier. The only decks I use Daily Casts in now are decks that have Aesop's Pawnshop or Career Fair. Both of those cards speed up the rate of return. Data Folding, if put on Supplier, takes 3 turns to make a credit, and in five turns makes 3 credits. The reason I still play them instead of Daily Casts, is because there's no upper limit. As long as Data Folding is on the board for 4 turns, it's making profit, and if it's on the board for 10 turns its made more than Daily Casts ever could. The counter argument to this is that why are you playing games that take 10 turns? The answer: Sunny. Sunny is incapable of ending a game before 10 turns have gone by unless you're exceedingly lucky or the Corp is exceedingly bad. This is why NEH Fastro wrecked her so badly.
(Speaking of Kati. In 9 turns, if you store/store/take which most consider to be minimum efficiency for Kati, you'll make 16 total. And have spent 9 clicks. Compared to Data Folding, you spent 9 clicks and made 9 credits more. So at Kati's minimum efficiency standard, it performs worse than Data Folding. The actual problem with Kati is that she doesn't give you money each turn, and Sunny wants to reach a point where she can afford at least one run a turn.)
I agree, Peddler is good speed, and I think that if you play OCA + Faust, Peddler is acceptable. The reason there is that if you play OCA + Faust, Peddler's value as a speed card is maxed out, and since you're playing Faust, you shouldn't care about losing any two cards that it could hit. One of the reasons I've moved away from Peddler is that I've found that I can set up and still have 15+ cards left in my deck, as long as I can search my deck for what I need. Sunny doesn't need to draw All of her cards, she needs to draw Nexus, her breakers, and UWC's (and any other drip/recurring econ to be able to use her suite to get into One server each turn.)
Faust is Faust. I agree it lets you threaten remotes with a single install, but I contend that's not what Sunny is trying to really do. I feel Sunny is similar to an Iain build, where you're going to lose the early game, so we're trying to make sure that we crush the lategame instead, and make sure we can get to that lategame. I feel Faust does slow down your setup, by a bare minimum of a click and 3 credits' worth, and more likely, since you're clicking to draw, by one click for every card used on Faust. Slightly less than that, due to OCA, but it's a comparison to be made. I do like that it lets you use your cards instead of your money, but I'm still thinking that might be the wrong way to go? Just because we can, doesn't mean we should.
With Sandburg, Corps hoard more money. They can afford to beat one Nexus trace, at least. Having higher Link (and Power Tap) makes it hurt more when they do it. I think that's the main reason I still like LinkSpam Sunny, because if I can't get in, then I've at least made all your ice -1 Strength if you keep me out.
I do think that this is a good OCA Sunny deck. I'm just not sure that's it's the best Sunny deck.
