Looking for help on LOL XIII-XV

Hi all,
Relatively new player who's been working at building up his roster and talismans. I finally got to a point where I started taking a look at my keys (slow start as I wasted a few early on). Since I can farm LOL X on auto (all colors), I took a shot at LOL XI-XV. I can farm LOL XI and XII with no problem at all. Once I hit XIII, I just get abused.

I found a guide on this site.. but unfortunately I'm missing a bunch of the recommended characters and talisman sets. Regardless, I was hoping that someone would be kind enough to take a look at my roster and let me know if I have a viable team that could take out LOL XIII - XV?

My current team is as follows:
Gambler Edie (Chance, Fate talismans)
Warrior LOL (Viper and 1 Stone talisman) - awakened once
The Madam (Singularity)
The Killer Prime (Vorpal, Ruin, Cosmic)

If there are other characters/talisman I should switch to, no worries at all. I enjoy farming, so it's all good. Any advice would be graciously appreciated.
