Decided to yoloroll once, got a Nim.
That's... not bad I guess.
Edit: If I'm gonna focus on attackers I need to pick a color.
Red: Nim, Freyr x2, Ares, Asuka, Ame no Uzume, Dino Rider, Leilan
Green: GZL x2, Liu Bei, Kano, Thumbelina, Sasuke, Michael x2, Leeza
That's all the REM stuff I have; they both have farmable options too. I'm leaning heavily towards green atm because I can run a straight up Three Kingdoms team with that color, even if it's not ideal :V
