It seems random (I managed to get reversal on the first turn while 2 minions were still up). The boss could undo his reversal with another reversal (I think I get reversed 4 turns in a row once, at least it's a damage free turn). I want to do more testing, but it appears closing the App gives you a chance to avoid the reversal (or it might do it again anyways), it would just take time to get back into the fight (hope your internet is good). But when the beast reversed me right after I took out the minion and I closed the app, when I came back into the fight, I appeared to have not received the minion boost (and the beast did a damaging attack). I don't know if closing the app always loses the boost or only if you close it right after getting the boost (normal attack is better than a debuff, I suppose).
