Mars + Outworld Destroyer

Why this works

Failing to secure objectives after a good fight is a common theme here. The core issue is how their spells interact. Mars wants to trap key enemies in Arena of Blood so the team can focus them with attacks. But Outworld Destroyer's Astral Imprisonment, a key part of his own kit for setup or survival, makes a target immune to damage. An OD using Astral on the main target inside the Arena completely wastes the setup, as nobody can attack them. It creates moments where two big spells cancel each other out instead of compounding their effect.

This awkwardness means their mid-game power spike often fizzles. Instead of a clean kill inside the Arena, fights become messy. The Outworld Destroyer player is forced to think twice about using Astral offensively, limiting his own impact, while the enemy gets extra time to react or counter-initiate. To succeed, the Outworld Destroyer has to play with incredible discipline, saving Astral only for heroes outside the ring or for saving Mars himself. This requires a level of coordination that's hard to achieve, making it easy for opponents to exploit the clumsy follow-up.
