Japan has the French problem of having too many useful cards for 1 age. France has a lot of good Age 2 cards while Japan has way too many strong Age 3 cards especially with the new Team Odzutsu Mortars.
Please move a few of the stronger cards to Age 4. In particular the new card should go to AGE 4.
A rework of Sword Saint for Samurai and moved to Age 4 would also be great.
