How to active Unit cards?

[Radious]

Can anyone help me? I have new cards for my custom units, but i dont know how to activate them in the game so the cards are on the custom units.

Which tables and with what must be edited so the cards i have will be on the units i made?

Thanks for answer.

The unit card 's name must have the same name with the variant model 's name.
Example: you have the katana levy; the variant model name is genpei_inf_samurai_katana_levy; so the unit card must have the same name like this.
