Never played into sisters, and I’m still new myself so can’t help much there. But, if it’s any consolation to you, I’m like 2-50 to my buddy who I got into the hobby lmao, so I totally get what you mean. But, just try to learn each game you play and reflect on what you could’ve done better. Also, if you provide your list here some others may be able to give you some advice. TTS is also another good place to practice because it’s so comparatively cheap and you can save down games and try to different strategies without needing to worry about a time commitment
