Best early champions to snowball silver games?

In lower silver I found it sufficient to play a farming jungler like Shyvana that could wreck mid game, only taking ganks that presented themselves but not trying to force anything. Now more mid-silver that's not working as well.

One person suggested that the way to carry silver is to use a champion that will crush a lane, and tilt one of the players, leading to easy victory. I had previously assumed an early gank and lane crushing strat wasn't working for me because my team was never good enough to take advantage of the early gains to turn that into a game win. But maybe now they are getting better at doing that.

I've played a lot of Talon and Quinn this way in the past. Win lane, roam to gank. Or don't win lane, but still roam to gank. However, they've gotten nerfed a lot since I last played. And top lane is no longer as impactful it seems.

Options I'm considering (I am open to other suggestions):

Jungle: Udyr Jax Evelynn

Top: Fiora

Mid: Katarina Fizz

Ones that people say are good for this, but I'm not sure because I never played them: Akali (Mid) Shaco (Jungle)

Of those, it seems Evelynn and Fizz are more likely to snowball games than the others at this level.
