Tai's semblance should be named: "Stack the Deck" and it allows him to change the face of any card he chooses. However, he can only use the ability 13 times per deck.

As for Inari, her Semblace will be named "Foxtrot". As long as she is locked into 1-on-1 combat, this Semblance allows her to improve her movement and attack speed.
