I really newbie in this game so maybe someone can give me tips on reroll?
When I first went through the beginning I had tamarine, bellona and iseria but I read in the guides on the internet to look for destina, so I made a new guest account. When I was doing it 2 times I went to reddit and read that RNG was good for me, but because of lack of knowledge I destroyed my good start.

So I have questions:

Currently, I managed to save tamarine / ken / kayron - is it a sufficient team to go through the campaigns without major problems?

What rules to follow when choosing? When I get for example: Bellona / Iseria and Vindred / Sez - is it simply to lookin for a healer for a team like Angelica / Destina / Tama?

Currently, I am guided by the principle: If I do not draw in the cards Destina / Tama / Bello / Vindred / Sez, I start again. If one of them falls out, I try to look for a sensible pair after completing 1-10.

I do not aim for a perfect team, I just want to go to the endgame without spending a lot of money.
