Darth Bane LST

The OP explicitly said LST (meaning Lightspeed Tokens) and Conquest characters will never be in LSTs

I'm assuming you mean LSB (Lightspeed Bundles) and yes there's a Darth Bane LSB

Not true. He was in the store as a LS. Thats how I got him. 

Thank you for the clarification 😃

No, because he is a Conquest unit.
