Returning unit here, what are some recommended good units to get?

My current squad has guinne, maeri, sennie, Phaedra and sun kissed tilith. I’m looking to get Kranus for the selector ticket. Some notable units I have are cozrag, cayenna, fennia, Annette, xenon, ciardha, set, kranus (dark), persenet, kyria, vail & vidron, hinoko & hisa, vanilla, gwenevere, Karl and beserk Ezra

I’m not sure what to form a team with as I’ve been so out of touch with the game, thats why my team consists of mostly new units. Would appreciate if someone can appraise my squad and give some suggestions. Thanks!
