Baby Apples and Fishies help!!

Ok guys I'm gonna be real with you, I'm both a baby apple and a fishie lover but I can't decide what I should do. I know that Caleb's birthday is coming up really soon and there's also Raf's new muth coming up. I low-key love them both equally (even though I kinda main Caleb.) Typically I would go for Caleb's birthday, but I don't know...

Generally speaking I have more Rafayel/Zayne cards more than any other. I don't really have any of Rafayel's myths and I haven't been very lucky with my pulls. I thought about pulling for Caleb because I don't have any new cards of him, but honestly it's just so hard to get him. I don't know if my relationship with Caleb is one-sided or something cuz that boy BARELY gives me ANY CARDS, both in pulling in general and in the explorer!

I know Caleb doesn't have as much content as the rest of the boys do, (especially with Raf's new myth coming up), but idk.

What should I do? Should I pull for my main fav and try to get more cards of my apple boy? Or should I save up for my fishy god(dess) and try to pull for his myths? Just to let y'all know as well, I'm the kind of player who lately only does the bare minimum. I just log on, do my dailies, sometimes tap on the boys and leave. I'm also f2p so that's very helpful... Only got 3325 or something diamonds last I checked... Will I have enough for them? I know I can only choose one so I need the girlies who actually do the hard girlmath for me to help me decide and figure out what I should be doing with my time, and if I wanna go for any of these guys....

Thank you for your time!
