The Pub Breaker [6.80]
People used to cry "OMG SPIRIT BREAKER IS SO UNBALANCED! VOLVO FIX!" Well... patch nerfed him a bit, but I hope with my build we can fix him. I usually go on Solo Hard Lane with him because I like to know that there is some hard carry on easy lane who can Carry game if i fail with ganks, but SB is also good on Mid vs melee heroes like Pudge and can carry well on Easy lane. In my build I tried to show you a few combinations of items depending on situation in game. You will find here "Offensive Items", "Defensive Items" etc. I tried to explain why would you buy this item, not some other. Feel free to show your point of view in the comments, maybe I'll learn something. Good Luck with Breaking Backs!
Item win rate statistics are just bonus, They doesn't mean that some item is good, so I leave them to your own thoughts. For example Power Treads have 51% Win Rate, so we can guess because they're cheap, and one of first items they can't have bigger meaning in the game. BUT for example if you can buy Cuirass (80% WR) early you can see if you're doing good. Good Luck again!

WORST VERSUS (January) FROM DOTABUFF
-Meepo ( I don't think I need to explain it)
-Treant Protector (Treant shield is very good vs ganking SB)
-Omniknight (Omnis every skill counter SB)
-Clockwerk ( He's mini-stuns will stop SB from charge and ultmate)
-Naga Siren (Just web, ult if web isn't enough)
BEST VERSUS (January) FROM DOTABUFF
-Nature's Prophet (just "charge")
-Pugna (SB [if lucky] can do many bashes, and they can stop Pugna skills)
-Earth Spirit (I guess SB ultimate made big impact on statistics)
-Clinkz (just "charge" + dust ;D)
-Keeper of the Light ( low KotL hp )
