The core of the deck is a high variance move: the astro chain. Which is a combo where you must assemble the right cards together, typically in the right order without the corp interrupting you (previously: biotic/astro/sansan & cash vs legwork/imp; currently: biotic/astro/sansan/shipment/cvs vs legwork/imp/clot/clone chip/smc)
The rest of the deck took this highly variant combo and wrapped it up in a very tight and consistent package, but the core of the deck is this high variant monster we all have named and choo-choo'd numerous times. How do we know this is a deck which utilized a high variance tool and not just a really good consistant deck? When a tool came out that targetted the high variant portion of the deck, the deck required serious changes and its win rate dropped severely. The entire deck became high variance where it started waffling between hard wins and hard losses.
High variant combos and moves are very powerful, and when you can wrap them in a consistant framework they become THE DECKS to beet. Other decks that fit this model are: noiseShop, 7PointShutdown, and siphonSpam. These decks were nigh unstoppable until the meta answered them. Granted, in some cases there were additional strong consistent components to these decks, but they were mostly one-trick ponies and those consistent pieces were placed to push the high variance move to happen more frequently.
- All the agendas got milled
- I got all the agendas scored in a single turn
- My opponent can't ever have cash and hence defenses
It would be wrong to describe these decks at the point that they were peek performant as just "high-variance" decks, but ultimately that's what they were. Variant combo decks that were given enough support to become temporary monsters until answers appeared in the meta.
If you are deck building and you find a component that is high variance and helps you win games, it may be the first component of a deck like these. You catelogue that information and return to it, comparing it to newly released cards until you think the scales have tipped enough for you to take advantage of it.
The win rate is what ultimately matters. The article isn't wrong about that. But recognizing raw power and how to harness it is an engineering skill you want to have.
