After playing for a while i have to say that the Star of Festa mode is really disappointing. I can understand if they give different point totals for songs of different difficulty ratings, but it essentially locks you into playing a select few songs over and over again just to get a S or better result because the difference is ridiculously big. I tried SOF expert mode and the only way i could clear it was by spamming 9/10 difficulty songs, and given how important familiarity is at higher difficulties i ended up using the same 3 songs every day. You can't even get 20k points in 1 day for a bare minimum clear even if you 100% SSS 3 8 difficulty songs, that's how restrictive the mode is. At this point i would pay good money for a 'unified' game containing all the songs so i can at least have some variety in SOF mode.
I'm going a different route to that problem: farming name cards. To do so, you leave the first 2 songs to the idols and take as 3rd song whatever you like. You should be good with the song, preferably be able to full combo it. It doesn't need to have a high difficulty, because your rival is limited to the same songs as well it seems. I could easily beat all 3 Jupiter members (the only SSS rivals i'v seen so far) by playing "Music", even though it's just an 8 star song. I could also beat SS idols with 7 star songs without (didn't try it against jupiter on those).
If there is no new rival you can get a card from, just restart the game. If you loose the song you can restart the song and try again without penalties or the need to wait/go through menus again. I admit it's a bit tiresome, especially when you already have a lot of name cards. But now i'm at about +1800 points and after this "farming run" on expert i'll give it another shot on clearing expert.
With an 8 star song you can get 5850 points quite well. If it's the 3rd song and you beat a rival it is somewhere around 6700 points. This makes 18400 points, so you need about 1600 points from name cards. If you got that, it also "unlocks" the 8 star songs for expert SoF. I don't know how many points you can make with 7 star songs.
Btw i went this route not because i was tired of playing the same songs over and over, but because i wasn't good enough with the 9 and 10 star songs. Though i haven't tried them for a while now, i assume i got much better by now, considering how much "easier" the 8 and 7 star songs have become :p
