here are some on the top of my head:
- Lone druide ranged build with main hero
- Axe right click with manta
- Batrider right click with manta
- Zeurs right click with manta (this one is still relevant)
- Pudge pos 1 (this one is still relevant too i guess but rare)
- Lina pos 1
Pos 5 PA before they nerfed the shit out of early dagger.
Pos 5 lifestealer for like a month before they quick fixed AGs after realizing how broken it was. (Just AFK in your carry all game and build auras)
Pos 5 AM
Pos 5 morphling before they nerfed that.
