Shadow Demon
[wiki] rating: -0.6 (winrate: 48% pickrate: 2%)Lone Druid

Spectre, Shadow Demon, Phantom Lancer, Naga Siren, Chaos Knight, 
Terrorblade) or bring other units into the fight (such as

Templar Assassin
[wiki] rating: -0.6 (winrate: 51% pickrate: 5%)Tusk

Doom
[wiki] rating: -0.4 (winrate: 46% pickrate: 3%)Lone Druid
* Besides Lone Druid and Meepo, Doom is potentially good versus every hero since Doom will render any hero helpless for a prolonged 15 seconds. This is particularly true for fragile heroes that heavily rely on mobility to stay alive.
Lone Druid
