CLS Lead Arena Team Is Nuts

So already in my shard is this lovely team:

Led by this man:

I fought 10 times. Lost every time. I haven't lost on offense in over a month.

I'm at a loss. No clue how to beat this team. It's all counters, stealth, foresight, taunts, debuffs and cleanses with 3 toons that hit like a truck attack. Any thoughts?


EDIT:

A couple shard mates in our discord chat took a shot including a zQGJ and Zaul lead with no luck.

UPDATE:

This team was eventually beaten by Rex lead, Thrawn, R2D2, Nihilus, and Shoretrooper. Guy isn't in our shard chat so I don't have specifics but do see that he remodded his R2D2 to be faster than everyone on opposing team (by a hair).

So the key is as a few of you have noted, you need an ultra fast Thrawn, ultra fast R2D2, taunting tank like Shore, and everyone's favorite standard toon, Nihilus.

Glad to see it can be done without GK.
