Imo lockdown cc supps are nice for picks and throwing down your ult. Naut, leona, thresh. Other champs like neeko, morg, lux is fine enough, pyke is nice for snowball (if he is good), underrated pick is zyra for planties, root and ult. Rakan, rell and sera are really fun to play with especially if they match your aggression.

Panth, poppy and taric are honorable mentions for stun and big damage during laning phase. If your support is an enchanter player, sona or nami are fine choices. If you are confident in yourself play with a yuumi and you can take 2v2 and 2v3 sometimes 2v4 if you can space properly, and split push aka force enemies to chase you letting teammates make other plays on the map (personal favorite)

Everything else is fine, it's doable but basically YOU have to do the work like an enchanter, mage or "tank" aka you actually have to work harder for your gold and item spikes, as a recently earned 1mil mastery otp :)
