REVERSION EFFECTS EVERYTHING IN A FIGHT EXCEPT FOR THE PEOPLE WHO ARE STILL ENTERING BUT NOT YET IN SAID FIGHT. IT UNDOES STYLES ENTERED, BUFFS DONE, DEBUFFS DONE, GENJUTSU EFFECTS, POKEMON CAUGHT, TAIJUTSU EFFECTS, PATHS SUMMONED, WEAPONS EQUIPPED, AND ANYTHING ELSE THAT HAPPENED IN THE INTERIM. THE CURRENT ROUND IS THEN MODDED WITH THE SENT ACTIONS FOR THE CURRENT ROUND AND IF THE NEGATION OF THE PREVIOUS ROUND MAKES YOU UNABLE TO PERFORM THOSE ACTIONS THIS ROUND THEN YOU DO NOT PERFORM THEM.
For future reference - If you have any questions relating to how something works in the battle system and you do not like the answer your mod gives, do not continue to argue with them. Come to me via IM, PM, snail mail, email, smoke signal, carrier pigeon, dial up, high speed broadband, fiber, firewire, sczi, hmdi, vga, serial, coax or any other method you can think of.
