Tips

 * Joker is one of the most useful character to net battle accomplishment points for 2x EXP.
 * His passive can ensure you get a Bonanza, which is a bonus that usually requires luck.
 * His Voltage skill does 260% damage, giving him a decent chance of landing an Overkill.
 * You can string all the above together to get the Overkill+Bonanza+V Finish bonuses in a single kill, giving you 14 of your 20 required points for the 2x EXP bonus after battle. Considering using this particularly if Joker is not one of your main line up, since you can save him for the boss fights. Just swap him out afterwards so he doesn't hog EXP.
