Always(!) start Top-Side so ur botlane doesnt loose from the beginning use ur e to reload dont smite red or blue but rather wolves/raptors try to get crab early for vision and search for cross map counterjungle opportunities for ex: enemy jungle ganks bot u invade his top jungle
try to gank early often so u can start to snowball.
Also gank ur top/bot lane early and help them to push(u have strong push power) to get 1st turret.

As soon as your team starts to group either try to get picks or flanks. As graves u can also try to catch splitpushing opponents

Obviously try to get as much farm as possible use ur e to reload or to dash over walls counterjungle your opponent

Thanks for reading my guide im greatfull for all feedback.
