Emperor’s Children Playstyle

I am somewhat new to 40k, I mean sometimes I barely understand my own army (World Eaters)

I know we don’t have the full picture as they are just revealing a few bits and pieces of detachments but from what we have, what is the playstyle of Emperor’s children looking like? I should also probably not look into it too much since my wallet would not like me getting a new army but we ball

I know for the other chaos legions is sort of: - Death Guard: slow, somewhat tanky and if they get close they will give you syphilis - World Eaters: strong in melee and what is a shooting phase? - Thousand Sons: Shadow wizard money gang
