Left to right
Uppercut minions with bomb into enemies to build stacks
Removed Burst and added Reach to reduce the amount of "Ghost Cast" bugs due to the short cast range of Bomb

Left to right
Mystic Vuln flex slot 1
Play agressive and build bomb stacks

Buy other later

Sell Spirit Strike
Self-Cast bomb and phantom/warp into enemy team
Remember to change self cast setting to Modifier Button
A lot more players counter with Debuff Remover now so that's why we self cast lategame
Try to land Uppercut right before the bombs go off to apply Mystic Vuln and Soul shredder (for the %spirit amp)

Knockdown helps hooks
Silence against immunes
Buy Curse if they buy Eth Shift

The focus on this build is to build up stacks on your bombs by doing damage to enemy heroes as often as possible
Don't be afraid to farm for Echo Shard since it will speed up your bomb stacks alot
Practice placing bomb on your own creeps and uppercutting them into enemy heroes for surprise harass and free bomb stacks
Skill order 2-3-1-4
