Enigma + Invoker

Why this works

Landing a big Black Hole sets up a perfect canvas for Invoker's damage, especially for a well-placed Chaos Meteor and Sun Strike. In theory, this is a teamfight-winning combination that can wipe an entire team. The problem is that it relies on two of the longest cooldowns in the game being available at the same time. If Enigma gets his channel cancelled, or if Invoker is out of position or doesn't have the right spells invoked, the entire play falls apart. This makes their big teamfight potential very high-risk and inconsistent.

Both heroes also demand a lot of resources to reach their peak. Enigma needs to farm a Blink Dagger to find initiations, and Invoker always needs levels and farm to be effective. This can lead to a greedy early and mid-game where your team struggles to keep up with enemy pressure. The entire game plan often revolves around landing that one perfect ultimate combo. When it works, it feels unbeatable. When it fails, you're left with very little to fight with, which is why having both Enigma and Invoker on a team doesn't consistently lead to a win.
