Snapfire + Storm Spirit

Why this works

Thinking that Snapfire's ultimate will set up a mobile carry often leads to disappointment. While Mortimer Kisses provides damage and a slow from a safe distance, it creates fixed zones of danger. Storm Spirit wants to be zipping between targets and choosing his own angles of attack, not feeling tethered to a specific patch of burning ground to get the full effect of a teammate's spell. A Firesnap Cookie used to "help" can also easily disrupt Storm's own kiting and positioning, forcing him to waste mana repositioning after an unwanted leap. The lockdown from either hero isn't quite enough to guarantee the other's damage lands perfectly.

Across a game, this pairing can feel disconnected. Laning and early ganks might look fine on paper, but in chaotic teamfights, Snapfire is usually trying to shell from the backline while Storm Spirit dives deep into the enemy team. Storm needs instant, reliable lockdown to hold a target for his burst, and Snapfire offers slows and a delayed stun that are better for peel or counter-initiation. The duo can certainly win fights, but they don't amplify each other's strengths. They often feel like they're fighting near each other rather than with each other, which makes closing out kills less reliable.
