Rebels Basic Training Event

Ah, that did the trick. Everyone kept telling me that all I needed to do was stun Thrawn, stun EP, and then kill Thrawn and kill EP. Then when pressed, they said you need to ability block the Stormtroopers too. But what they didn't say is that you need to play as defensively as possible. You need to stop the other team from doing anything at all, and about the only one you can let go is Vader and only for one turn. I guess TFP might be able to get away with a turn and not destroy your chances of winning. To do that, you need to stun and ability block as many characters as you can, and you need to do buff immunity on the Stormtroopers in addition as much as possible. But stunning them is great too. Forget about damage until everyone is knocked out, except when you have a character that can't do anything except damage because their defensive moves are on cooldown. But prioritize Leia's stealth, R2's stealth (as long as Ben is alive), and Han's crit moves over doing damage too. Then take out Thrawn, EP, Vader, TFP, Stormtroopers in that order. Once I figured out that strategy, I did it in one attempt.
