Tarkin destroy the Meta - Video

I like this team. I have problem with draws. My Empire is strong enough to beat every team but my iphone is lagging. Many times i cant win couse of not enough time. So Tarkin could be solution for this. Also i think to put bb8 for increasing dmg. Advantage and crit chance and crit dmg up plus offense up would improve Tarkins dmg a lot. And I think Tarkin could have les turns to build up potency. I dont want to use Palp. He is too low with health/ prot.
