Are you planning to do some costume pulls? I know the odds are low but you may be getting Marjana costume.
She would be an asap hero to be maxed. Good for raids, wars and titans.
Do you plan to emblem any of them? Marj with emblems can make some damage. She has a dot like your GM but you can always aim to another target with her.
How is your red attack team? Mono red?
All your options have something good and new to add to your red squad. Marj add fire power(better if you can emblem her) , tyr is sticky as hell , doesnt hit as hard as an sniper but can carry a match.
Vanda is really useful, like Grazul to overcome this dot meta. So , its not easy to recommend you one of them. If its based on personal preference i would do
Vanda - Tyr - Marj
I picked Vanda because shes v.f like your GM and the aliment protection , fired on time, can be game changer
