okay so i started playing sifas, like, two days ago? and i'd like to get some tips because i don't know how to make some things in the game:

• first of all, how many good cards should i have to complete hard/expert lives without failing? i have 3 or 4 GD SRs and one UR which is not GD so idk, i guess i need to scout more

• i'm almost at 1000 loveca stars, should i scout now to try to get some good cards to start or wait for the next gacha? because i think the next gacha will be either nico or rin and the next event will be mari, i love all of them so i guess i'll save

• related to events, i guess that i have to make points by playing songs, right? i understood that i can skip lives with skip tickets after getting all three rewards for them. and i remember the minimum position i need to get to have the event card is 50.000?

• last thing: to idolize cards i need those crystals with the idol's face on. i understood that i can get them either with playing songs with that idol in (for example i need chika's, so i should play aqours/cyaron/chika's solo) or to bond-level-up that idol. but for the bond level it takes me a lot, (i played for one hour and leveled up chika from 1 to 3 only) is it because i play songs in easy/normal?

tysm to everyone who will answer, i barely understand basic commands in this game ahdskkbshgd
