So far, we've (kinda) eliminated Drizella and Regina. I also think we can  eliminate  Zelena &  Lady Tremaine as well.

So, that leaves us with, in my opinion, the following...

1. LEOTA [the only witch I know that's related to THM]

2. MORGANA PENDRAGON [we didn't see her in S5]

3.  DR. FACILIER [a wild guess IMO, but who knows?]

4. YZMA  [another wild guess IMO, but who knows?]

5. AN UNKNOWN WILD CARD
