Enigma + Shadow Fiend

Why this works

Stacking Black Hole and Requiem of Souls sounds like an ideal combination, but in practice the two ultimates often compete more than they cooperate. Both spells are designed to win a teamfight by themselves, so using them together on the same targets is frequently overkill. A well-placed Black Hole provides all the control needed to secure a fight, which can make Shadow Fiend’s ultimate feel redundant. Both Enigma and Shadow Fiend want to be the centerpiece of the engagement, leading to awkward positioning as they both try to find the perfect moment.

This overlap forces the team into a predictable rhythm. Your strategy becomes centered around waiting for two of the game's longest cooldowns to align, creating large windows where the enemy can safely pressure the map. If that big teamfight combo doesn't connect perfectly, you've invested massive resources for little return. While the potential for a clean wipe exists, the lineup often struggles with tempo and can feel inflexible if the enemy refuses to group up for the dream scenario.
