OverDress Card Intro: Diabolos, "Violence Bruce 

Every card skill seems nutshelled in Overdress, so full context for this one:
[AUTO](VC):At the start of your Ride Phase, you "Final Rush".
[AUTO](VC):When this unit attacks, if you are in "Final Rush", COST [Soul Blast (5)], and [Stand] all of your front row rear-guards.
Final Rush is a skill that empowers player for the rest of the game once it's activated by certain units that use it, if that's right. Like some of Buddyfight's Overthrow effects that are used for the rest of the game.
