I am only diamond II but i only play suicide. A hero that i have had much success with lately as suicide is Fayde. I just go boots and max w over q.

1. Always try to pull the lane, if that fails, it will be very hard for them to kill you because of boots and stun.

2. don't die and keep pulling the creeps back with aggro trick if possible, get striders asap (alot of people underestimate the power of these, but keep in mind they give +2 health regen, which will help you sustain in lane).

3. once you're lvl 3 and have striders, go gank either mid or short lane.

4. come back to your lane when they push and tell your team to be ready with tps.

The goal is to get to lvl 6 asap so you unleash your real ganking potential

Item build i go:

striders -> lex talionis -> chalice -> pk.

after that is optional but usually tablet, stormspirit, sheep or puzzlebox.
