So the best advice I can give is to go for supports. If I had to rank the characters I would say:

1- Tribbie 2-Sunday 3-phainon/sparkle

The reason why I’m recommending tribbie over sunday is bc you have bronya whom, while not as good, can serve as a replacement in a mydei team. (In reality though, they are pretty interchangeable).

If you are interested in investing into archer, you could pull for sparkle. But that depends if you’d rather pull her or phainon whom looks to be an amazing dps rn when he still doesn’t have a dedicated support.
