Arena team against JTR (no Thrawn)

I'm typically hovering around the 50-100 range on my shard, and don't generally have any trouble beating JTR teams. I run an Ackbar leader with Commander Luke, R2, Hermit Yoda, and Thrawn. You've got to control General Kenobi and R2 with stun and fracture (these two characters seem to be a staple of every JTR team). Then pick off BB-8. Once BB-8 is dead, the match is won.

JTR teams rely upon BB-8's Illuminated Destiny, so all you've got to do is deny BB-8 the ability to use it.
