The latest Shadowfist expansion finally arrived, after a long hiatus. So I built a few decks and went off.
Amusingly, for the first game one (strong) opponent had built a deck using the same basic character structure. In fact, our decks were distinct. That's one of the reasons I like Shadowfist.
[In order to keep this short, I'll put the Magic: The Gathering equivalences in parenthesis ()].
So, our fact (color) was the same, and our characters (creatures) were the same. But we had made fundamentally different choices in site structure (land/power gen). Unlike magic, power in Shadowfist is all 'colorless' ... there is a colored requirement, but creatures provide it. This frees up land to have special abilities, but be used by any faction (color).
In fact, all of the CCGs I've really liked have this property. It's a sort of ... orthogonality, of deck design. To summarize it ... there are two (or more) parts of the deck design that work at different angles. In shadowfist, no matter what faction I play, my power generation choices are not tightly coupled. In Magic, they were (to a certain extent). If I played a Red deck, I had mountains (or the rarer counterparts). But if I play Architects, I could use sites that generate extra power, have extra defence, provide push through, protect against specific decks, or whatnot.
In Legend of the Five Rings, your faction determined your dynasty deck fairly tightly, but the fate deck only loosely. Most fate cards weren't tied to a specific clan. In Netrunner, your running strategy didn't completely determine your suite of icebreakers.
Now, in all of these cases the decisions aren't truely orthogonal. Some site strategies will combine with certain decks better than others. So it's not completely seperate, but loosely coupled.
This really opens up the deck design. Even there are n factions, and then I have an 'orthogonal' decision of m sites, that provides n times m options. As these rise, the 'basic deck archetypes' square. If their additive, then it's a linear growth.
This isn't saying that Magic doesn't have this. It just did, to a much lesser extent. (And this is based on when I played, a decade ago). Shadowfist, and all of the non-Magic CCGs that held my interest, has this property.
