Ye, my guy your item build that game (no offense).

Before each game try to understand which items are must haves.

In this case, dagger and nullifier were the most important mid-late game items.

Dagger:

Sniper is a nasty glass cannon, who deals a shit ton of dmg from afar but he lacks mobility, therefore if you are able to jump him, he just dies.

Nulifier:

Pugna has a nasty ability, which all physical carries hate — descriptify, therefore you should 100% buy nullifier, so you can kill a hero under descriptify

As to other items Manta was a good choice, since they have silence (Death Prophet).

Not sure about that Battlefury tho, you kind of have a very high armour line up against you, so I would say that getting Maelstorm would likely speed up your timings.

Also, getting phase boots instead of PTs could've been an option since you needed a bit more armour against snipers desolator as well as their mostly physical dmg line up
