Character Strategy- Mother Talzin

Speculative:
You will need GG to unlock Talzin. 2 reasons, 1) it fits the narrative of the show. I have been told GG defeats Talzin with a group of droids. Clarification would help if this is incorrect.
2) Most people have enough other separatists and all 5 NS toons unlocked to very easily get Talzin. This will sell zero packs, however, and is not profitable.
My hope: any 5 separatists or all 5 NS to get Talzin. Or even a marquee event so you can still catch Talzin and keep her on the bench.
