Mmmm... Katya's pic is the one with the anniv patch date, so she would be the first pic. So, yeah, high chances that's she's the banner girl and Tess is the fre unit.

There's is a small chance that the free unit might not be a support, We got Vidya in 2.8 as an universal support. The free unit of 3.0 could be a subdps or dps.
