Bane + Ogre Magi

Why this works

A Nightmare setup into an Ogre Magi stun can feel like a free kill in the lane. Bane and Ogre can chain their disables together for a long time, and a Fiend's Grip on top of Ignite and Fireblast is usually a death sentence for one hero. The problem is that both supports are almost entirely dedicated to this single-target lockdown role. They don't really augment each other's plans beyond that initial kill setup. Bloodlust provides some value for Bane, but it's not his main focus. They end up with a lot of overlapping utility, which can leave big gaps in their team's overall draft.

This duo is at its best when making picks around the map before a big objective. If they can find an enemy out of position, they can almost guarantee a kill and create a numbers advantage. In a full five-on-five teamfight, however, their limitations become clear. Once they commit their spells to one target, they have very little left for the rest of the fight. Teams with good saves can negate their entire plan, and enemies can often win the fight by simply ignoring the disabled hero and walking past Ogre to kill the vulnerable, channeling Bane.
