Just curious, and I'm not being critical here, but why did you decide to start with Samurai? I mean, when you say 'modern', I think that starting at Celestial would make more sense because the card design(not mechanically but aesthetically) switched then to the current design. It's entirely possible that my OCD is the only reason this bothers me, lol.
The biggest reason I started with Samurai is because it is the first arc with all nine great clans. I wanted the card pool to be as big as possible and also wanted the same support for all major factions. Mechanically, the cards aren't too different until you get to ivory, so it isn't so bad to work with.
