Faceless Void + Magnus

Why this works

Stacking two massive teamfight ultimates seems powerful, but the synergy here is often misunderstood. Using Reverse Polarity to set up a Chronosphere is frequently redundant; both abilities can win a fight on their own, and layering them wastes a huge cooldown. The more consistent benefit comes from Magnus casting Empower on Faceless Void. This gives Void a cleave attack, allowing him to damage multiple heroes at once inside his Chronosphere. This interaction is the real core of the partnership, turning Void's single-target lockdown into a source of area damage, but it's a far cry from a guaranteed fight-winning combination.

The game plan for this duo revolves around using Empower to accelerate Faceless Void's farm toward his critical items. In fights, success becomes a matter of careful cooldown management. An ideal fight involves Magnus using Skewer to group enemies for Void, saving Reverse Polarity for a later objective. The weakness is that opponents will actively try to split the pair up or bait out one ultimate to force a fight while the other is unavailable. If Magnus gets caught before he can buff his carry, or if Chronosphere is used defensively, the duo loses its edge and plays out like any other standard draft.
