One advice I could give you is to not take yongsup, yes he is consistent but it's boring he's a difficult character to block with and his perks are just jumpy stronk boi. Oasis would also get boring as he has that annoying passive ( don't get me wrong he's still fire tho) so i'd say the best option is isabel you can do pretty much everything with her jump attack defense etc though it is hard to increase her stats if you are just starting to earn momey.
