Juggernaut + Keeper of the Light

Why this works

Giving Juggernaut consistent access to Chakra Magic lets him use Blade Fury much more often. This speeds up his farm by allowing him to clear creep waves and jungle camps with his spin, and also makes him safer since he'll almost always have it available to escape a gank. Keeper of the Light can simultaneously push out other lanes with Illuminate, creating a ton of space on the map for his carry to farm. The laning phase itself doesn't have much kill threat, as Keeper of the Light lacks a hard stun to hold someone in place for Juggernaut's spin, so the focus is purely on economy.

The success of this pairing really depends on whether Juggernaut can convert that farm advantage into a win. The duo provides very little lockdown, so setting up a good Omnislash often falls to other heroes on the team. An aggressive enemy lane can also shut this down early by repeatedly diving the fragile Keeper of the Light and forcing Juggernaut to play defensively, negating the whole point of the combo. It’s a solid plan for accelerating a carry, but one that has clear vulnerabilities and asks a lot from the Juggernaut player.
