Disclaimer: I have never played Ayla, but I think the discussion here brings up interesting considerations about NVRAM.
I love how complex NVRAM is. A card in NVRAM is 1) accessible whenever you need it, 2) doesn’t take up space in your hand, and 3) is not in your deck. All of these are relevant and push you towards selecting different cards for NVRAM. Silver bullet you won’t use? Then it’s good for reason 3: putting it in NVRAM removed a useless card from your deck. Silver bullet you DO need? Then it’s great for reasons 1 and sometimes 2; you keep it safe from damage and readily accessible until you need it.
Expensive consoles like Ubax are PERFECT for NVRAM; they’re cards you don’t want to see at all until you need them, when you want to see them IMMEDIATELY. Security Nexus is another great example. I think Deep Data Mining is also great, because it’s a power card that you want to have when you’re ready for it. I would always put Magnum Opus in NVRAM in any deck that runs it, but it’s still not a great NVRAM card because the extra click grabbing it hurts your efficiency. Magnus Opus is a card you’d rather have in your opening hand, while consoles and powerful run events are better on NVRAM. In constructed Shaper decks, breakers (except maybe your fracter) are generally bad on NVRAM too because you can’t SMC then out, but they’re good in Terminal Directive because of the lack of SMC.
For the article, I wish a dummy card (Exploratory Romp) would have been dubbed for the three missing slots and treated as blank. I found myself wondering if the article was giving an inflated sense of how likely you actually are to find a 2-of card on turn 1 in a 45 card Ayla deck.
tl;dr: Don’t just think “Is this a non-efficiency card I want to see early?” when picking NVRAM; consider the effects it has on your entire deck.
