Need advice expanding my champion pool!
Hi I just came to ask for advice on which champions I should pick up to expand my pool for ranked in a few weeks. The type of champions I like are jax and irelia, who have mobility and are diving bruisers based off of auto attack damage that do not scale poorly into the late game. I heard olaf is similar but I also know olaf kinda scales badly so I wasnt so sure about him. I also tried fiora but idk I just dont like her that much. The champions dont exactly have to be toplane either, they can be junglers. Any ideas would be great. Btw, if it matters, my elo is platinum 5.
(very snowbally, scales well into mid-late game) 
(very strong in the jungle, good AA damage, naturally tanky and has great dive potential) 
(sort of a tanky version of Jax/Irelia. He's more of an "all or nothing" type of champ and usually falls off a little bit late game, but has a similar play style).
could all work well for you. They aren't as mobile, but they all pack a lot of DPS and durability.
