Lesser known URF powerhouses.
Alright, so the first thing I'm going to say is that I want to address a few champions who I personally don't see a lot, (and I play URF a lot.) If anyone has other cool ideas, please do share, I love to play many different picks.
Let me start with Rumble.
His passive is now a blessing but still a little painful. So rumble now gas VERY PAINFUL auto attacks, but you don't get to take as much advantage of the Danger Zone. But since his silence was disabled, he is now very strong.
Now his Q, straightforward, is now 100% spamming. The cool down is lower than the duration if the spell.
His Work, the shield. Yes, shields are need, but now he actually has some escape power with that speed boost. And it's cd is only a couple seconds, and helps negate return damage.
Now, probably my favorite part about rumble is his E, those electric harpoons It can be cast twice with a STACKING slow. The cool down is low, which makes me feel like I'm using a harpoon minigun.
Need I say much on his ultimate? Let it rain rockets every 20 seconds. It can now casually clear waves and poke onto engage. Honestly with building almost full ap, you're just about able to get a penta kill with your ultimate alone.
PS: I'm going to add more soon, I have more to mention.
Much strong...
Does surprizingly good in most match-ups, just start with crit.
Incredible pushing and nuking potential.
Such damage.
Perma shield and slow. Massive damage.
You think Shaco is annoying?
main and he's absolutely terrifying in URF.
. Perma ult + Perma Youmuus active + Boots of mobility + Phantom Dancer passive = uncatchable yi. Spam alpha strikes (which with IE and PD do crazy amounts of crit damage), while Alpha Strike is on cooldown meditate and take hardly any damage, rinse repeat.
I prefer going tank here, because it just makes him too good.
Passive: Nerfed cuz of urf stuff, but still ungodly useful for all abilities.
Q: YOU WONT DIE IF YOU GO TANK.
W. Only works with armor... so go tank.
E. STUNS FOR DAYSSSS DOESNT MATTER WHAT HAPPENS JUST E AND E AND E AND E AND E
R. BOOST FOR EVERYONE
. You can ult basically whenever you want, and in laning phase you can vault constantly off your lane opponent(s) or blind them with q.
The most dangerous assassin I've ever played, kills faster than Kat Fizz Akali whatever sht
Saw an AP shen today, scary as hell
absolutely wrecks both tanks and squishies alike, he also can take dragon at lvl 4 with his E being stupidly spammable along with his W and his Q great too, though it will still take him 6 seconds to go into stealth if he's hit
I've never seen anyone mention her when talking about strong champions. Her E prevents chain cc strategies and a good bit of magic damage + can always be up if it's never broken through. Her Q can be a near perma snare at max rank and can be fired like crazy. Her W can wall off an entire lane or quick farm a wave since you can place 2 down at once. Her passive makes the laning phase much more tolerable and can give her nice sustain later.
Amumu. Go full AP on this guy. Once you hit 6 you can completely take over pretty much any lane with ease.
Will of the Ancients or 
Rylai's first, personally I prefer WotA for the spellvamp recovery in lane. I usually start with my Q for the 1 second stun, higher damage, and potential level 1 cheese kills. I put a point in each skill then I level Q whenever I can. When I can't level Q, I level E. I pretty much ignore W after the first point. The CD on Q begins at around 4 seconds, but drops considerably with each rank, eventually rendering you a stuncannon. Pair that with your E, your R stun, and the fact that you're pretty much nuking your enemy, and you'll find that it's pretty fun to run around actually LOOKING for your enemies.
endless ghoul slam with the ult always being up meaning people have to be killed twice. He becomes a huge tank due to the passive and sustain, but can also deal some severe damage.
Dodge ball anyone?
Always has double q's up as well as w, late game just use his cult to wave clear mid from base, engage with his e and you will usually always blow up someone before they can do anything. It's unlikely a 
will even be able to let you before she dies.
She's probably known pretty well, but, timbers is always able to be used either to take down turret or to just kill anything. She can spam all her abilities and wave clear without much effort and she will kill most anyone that comes near her.
AP Warwick is a pretty strong pick. Late game, if you let him push, Hello will destroy your turrets. And if the enemy team comes in 1 by 1, they will NOT stop you. You will excel in 1 v 1's, but you have to be careful about 2 v 1's as you will usually die.
have you even tried this champ Charged Q's for daze
Permanent Ult.
, useless during the first like 4 mins of the game, get a 
, and 
, get yourself
, and a
