There are several comboes to make a samurai card go over 10 power/toughness, but non of them can do it alone:
1.
Konda, Lord of Eiganjo +
Takeno, Samurai GeneralBasically you end up with a 8/8 Konda with bushido 5, that is indestructible and has vigilence.
2.
Fumiko the Lowblood + 7 other attacking creatures you control
3. 4 x
Brothers Yamazaki +
Takeno, Samurai Generalthe last one with the brothers yamazaki wont work because the text specifically that only two can exist at one time.. though if you use mirror gallery it will work very well.. they would be huge..
