Lifestealer + Weaver

Why this works

Putting Lifestealer inside Weaver for an Infest bomb seems like a good plan on paper. The reality is that Weaver is a fragile hero who survives by using Shukuchi to stay invisible and Time Lapse to escape danger. Forcing him to be the delivery vehicle means he has to run directly at the enemy, which is the opposite of how he wants to play. If he gets caught by a stun or silence before Lifestealer can emerge, both heroes are often lost. The core idea forces Weaver to play in a way that gets him killed, making the whole maneuver much riskier than it appears.

As a result, the two heroes often end up playing separate games. Lifestealer wants to find a target, pop Rage, and stand his ground, while Weaver prefers to skirmish from the edges of the fight. This lack of a central, coordinated plan means they don't really help each other much beyond what any two cores would. Lifestealer can't enable Weaver's hit-and-run style, and Weaver is a poor choice to set up Lifestealer's brawling. They don't actively work against each other, but they don't build on each other's strengths either.
