Invoker + Morphling

Why this works

Putting two resource-heavy heroes on the same team can create a strain on the map. Invoker is one of the most level-dependent heroes in the game, needing experience to unlock his full arsenal of spells. At the same time, Morphling is a carry who requires a significant amount of gold to get the items he needs to be effective. This shared need for resources means that for much of the early and mid-game, both heroes are focused on farming. While a global Sun Strike can assist Morphling, the pair lacks an obvious, powerful lane-winning or teamfight-turning spell combination that would make up for their passive start.

This dynamic often forces the other three players into a difficult position, needing to create space for two cores at once. If the enemy team applies early pressure, it can be difficult for both Invoker and Morphling to find safe farm and hit their respective timings. An opponent can exploit this by grouping up and pushing objectives before this duo is ready to fight as a unit. While a late-game Morphling with an Invoker providing crowd control is certainly strong, the challenge is consistently reaching that point without the enemy building an insurmountable lead.
