Squad help.

Hi, I'm pretty new to treasure cruise and was looking for help with building a good team/teams. I don't really know that much about the meta or what type of teams are good for certain situations so any information would also be greatly appreciated. I also haven't spent any money on the game so far I have just been saving in between each Sugofest and then spending all my gems there when it comes back around, so I wanted to know if I should keep a lookout for certain units and try to save until they come into the shop.



Sorry if this post comes out all messed up I'm trying to do this on my old iPhone in the middle of the night.
