Is Wampa's second zeta worth it?

I run a Rex(L) team with Wampa, Nest, Thrawn and Nihilus. I can stick in the top-50, break into the top 15 on the best days. I have every zeta on this team except for the unnecessary leads and on Wampa's special. Does anyone who uses this team find that zeta useful? Seems like it would be a waste against the current meta as Traya teams will simply dispell the heal immunity and Bastilla teams will resist. Anyone have a different opinion? Thanks
