Snapfire + Ursa

Why this works

Pairing these two heroes often seems like a good idea, but their abilities can be somewhat redundant. Ursa needs a way to get on top of enemies, and while a Firesnap Cookie provides that, it's a role usually filled by his own Blink Dagger. A well-timed cookie can be a great initiation, but it doesn't give Ursa the hard, disabling lockdown he truly needs to secure a kill against mobile heroes. Snapfire's slows from Scatterblast and Mortimer Kisses are certainly useful for helping him stick to a target, but they don't prevent enemies from using escape items or abilities, which is Ursa's biggest problem.

As the game progresses, their ideal fight positioning tends to pull them apart. For the combo to work, Snapfire has to use her cookie aggressively on Ursa, which can leave her without an escape. More often, she wants to stay far in the backline to channel Mortimer Kisses, while Ursa has to be in the absolute center of the fight. This means they are often playing their own separate games within the same teamfight. The synergy can work for a simple gank on an isolated target, but it lacks the coordinated power needed to consistently win larger engagements.
