Sakura Arms: Kikou Kakumei (2017)

Expansion for sakura arms dueling card game, this expansion adds 2 new machine/invention themed megami:
Kururu(クルル) and thallya(サリヤ).
Kururu is the megami of innovation and madness. She does not care what sacrifices it takes to complete her machines. Her mechanic requires you to have played cards(not discard) in order to complete the required components(the card type determines what components it counts as). She is the hardest megami to learn , and will remain that way according to the designer.
Thallya is a megami who was formerly a human from another land/country. She rides a motorcycle and fights with a "sword-whip". Her mechanics revolve around her "fuel", an extra resource that many of your cards require to use, or can make use of. She also has the ability to gain unique basic actions via transforming(utilizing her S4 special card)While she has a high skill cap she is easier to approach than Kururu.
This expansion adds more difficult mechanics than prior expansions, according to the publisher it will likely remain the most mechanically difficult expansion.

Sakura Arms is a Japanese dueling living card game made for 2 players, in which players build 10 card decks from a limited pool in order to reduce the opponents life to zero.
