Let’s talk about this wish(selector) banner

I am pretty new to the game and always wanted to have Saffi, and Auguste. However, I hear that Auguste and Tristan’s roles overlap, and people do not recommend to have them both. I am a F2P and have Agatha, Cocoa, Taair, Nonowill, Beryl, Col, Sp Raw plus other free heroes. Personally I wan to go after Saffi and Auguste in this selector banner, and also pull tristan and Kvare. Any thoughts would be appreciated.
