I don't know, ha ha 😂😂. I just use servants that I usually use.

Buster meta + Art meta. Some heavy invested fanatics can afford even sporadic quick teams.

Muzerker is still viable but she'll be replaced next year by a far superior Art aoe Zerker. BB summer is very situational and niche.

@Karl Briganti so i should spend in what banner that may come? I have koyanshaka and a decente amout of sq but i dont know a good Buster that i like

Ibuki Saber is bound to come after the summer event banner. She's one of the strongest AoE busters in the game as of now. If you really need one asap, you might want to aim for her.

Although, I was completely forgetting the free SSR ticket in Da Vinci's shop. Have you already used that? If not, Saber Artoria/Mordred/Lartoria/Drake are all good buster farmers.

You have Koyanskaya? It is buster meta.

You have Castoria? It is arts meta.

You have Skadi? It is quick meta.

You have Oberon? Doesn't meta his third skill doesn't stack.

The meta is usually referring to the "most effective way to farm the highest node in the event", and with melusine and gong existing, I don't think that you even need any other dps honestly, just play with whoever you liked, because the game are more fun that way
