judging from the characters you have that are level 1 and your registered date it is safe to assume you are in a very young server, if so you can put shisui/4 star madara/orochi gnw/kisame samehada/6p/pain 6p/obito/kakuzu earth grudge as pos 1 and literally any other characters you want to fill your team. With the characters you already have you are not a "semi whale" you are a huge whale, not saying that as a criticism, just saying you are in a position where you have more freedom than most other players. so you might as well take advantage of that, just throw together characters you like and have fun with it, you essentially cant go wrong
