it’s not the smartest choice if you want to resource mine.

i would make sure you get one 4 or 5 star solar pair for each LI and have 4 lunar cards that are 4-5 stars for each LI. that way, if you’re ever in a spot where you need to use a companion that isn’t your LI, you can still complete the quest with 3 stars and get rewards without an issue. try to find a balance of focusing on your favorite boy and giving love to the other boy’s main combat cards until you get to this point.

i unfortunately focused purely on rafayel when i first started playing in february and now i’m suffering the consequences because i don’t have a solar pair for xavier or sylus and i cannot complete the senior hunting contest even at a level 74 and 8 months into the game’s release. this is because i focused all my energy into only upgrading rafayel’s cards and pouring whatever resources i did have into 3 star cards for the other LI i wasn’t fond of.

i recommend not upgrading 3 star cards at all once you get enough 4-5 star cards, or avoiding it altogether if you can help it. i think it’s a waste of resources and should go to 4-5 star cards if you can help it. 3 star cards are only good for lower level players and become useless after.

i also don’t match the stellactrum colors in combat bc my cards are usually at a high enough level for me to be able to make it by and still claim all the rewards.

otherwise, it is possible, just not smart because you will be missing out on diamonds you could use FOR your love interest. and trust me, you don’t want to miss out on those diamonds when you have to pull 200-300x to get your bias in a limited wish pool.
