Why i feel the random buffs are not random ?

[AGESISUS]

In double's PF, my tres chic always get a throns at begining of every fights. And opponents' jawbreakers always get unflinching when them enter stage, if them unlock volatility. Every fights happened the same situation. The buffs gain is not real random?

well voltality generally gives defensive buffs so there is some chance to get unfliching than enrage but it is random.
