Best lineup?

So, I know there’s been a few threads regarding where to place Clarissa, however, this is a little different. I’m one of the lucky ones who has pulled all of the following ( Tell, Vela, GM, Clarissa and I’m thinking place Poseidon in the fifth spot for my Rainbow Defense Team). Now it’ll be a while before they are all maxed, but what lineup formation should it be? I’ve seen Clarissa,GM,Tell,Vela,Yellow (Poseidon for me). But I’m thinking I should place GM and Clarissa on opposite sides since they’re both VF and other two are “ just “ Fast to balance it out . Anyone think it should be the other way or a better formation? Thanks !
