How do you guys play with a faster Vader against Sion/DN

I run palp, zader, Sion, dn, and thrawn. If my Vader is faster, I AB whomever is faster - palp or thrawn.

Then their Vader will force crush your team, your dn fills tm and you can increase CD's.

Need to make sure to block their first move after Vader, so if his culling blade goes off, the TM gain from debuff removal doesn't allow thrawn to switch TM with palp, or palp to just go on his own, to stun.
