what supp should i buy?
Ty
Ty
Nami
Thresh if you will take the time to master him. Otherwise nami or braum.
Thresh, one of the best Supp's in the game. Can hold lane against a 1v3 if your adc is bad. And you're Tanky late game so you can make plays for your team if they're not the best.
Pretty much, he offers CC, ok damage, a shield, an escape for a teammate, tankiness that keeps growing (infinite armor/ap), can make plays and is Tanky enough to survive.
