Keeper of the Light + Snapfire

Why this works

Giving Snapfire a constant stream of mana with Chakra Magic is the main idea here. It allows her to spam Scatterblast and the blobs from Mortimer Kisses without ever needing to return to base. This constant spell output is great for shoving waves and chipping away at towers from a safe distance. Keeper of the Light can add his own Illuminate to this push, making it very difficult for most enemies to contest a lane without committing multiple heroes. The pressure they can apply together is real and forces opponents to react.

The game plan for this duo is to group up early and start taking objectives. When it works, they can suffocate the map and build a lead by controlling the lanes. The problem is that neither hero is very durable or mobile. A team with strong initiators can often bypass the wave of spells and simply jump on top of Snapfire and Keeper of the Light, killing them before they can get their damage off. Their success really depends on whether the enemy team has the tools to get on them, which makes the outcome feel pretty random from game to game.
