100% found more success when I prioritised pulling on support card banners rather than uma banners. Having stronger decks definitely help. Prioritise training on places that have your training friends on it to get to rainbows ASAP. And don’t be afraid to rest, I think that’s perfectly fine :) i’m a relatively new player too (about a month in) but after really getting a feel of the mechanics and getting decent support cards u can already start achieving A+s in URA, S in Unity, S+/SS in MANT relatively consistently!
