Enchantress + Invoker

Why this works

Expecting easy spell combinations here is often a mistake. Enchantress doesn't bring the kind of reliable lockdown that an Invoker needs to guarantee his big damage spells like Chaos Meteor. Her stuns are tied to whichever jungle creep she has charmed, which is situational at best. While Invoker can use Cold Snap to set himself up, he often relies on allies for longer duration holds. Instead of enabling Invoker, Enchantress plays her own game, focused on dealing pure damage with Impetus from a safe distance and providing some team healing. Their kits don't directly conflict, but they don't have much natural overlap.

The result is a pair of heroes that can operate independently rather than as a cohesive unit. Early on, an Enchantress can pressure a lane with a strong creep while Invoker looks for Sun Strike opportunities globally. When they try to gank together, though, they have to rely on the enemy being badly out of position. Without a dedicated initiator on the team, they can struggle to start fights on their own terms. The duo's success ends up depending heavily on what the rest of the team provides in terms of stuns and control.
