Lich + Lion

Why this works

Pairing these two supports together creates a lane with a ton of single-target lockdown. Stacking Lion's Hex and Earth Spike with Lich's slows makes it very difficult for one hero to escape a gank. The idea is to chain these disables to guarantee a kill for your core. However, both heroes are quite hungry for experience to get their key abilities online, especially their ultimates. They also both have significant mana costs early on. While Lion can sustain himself with Mana Drain, this doesn't solve the problem for Lich, which can limit how often they can execute their full combo together in the laning stage.

The game plan for this duo revolves around getting aggressive pickoffs. If Lich and Lion can successfully roam and find kills, they can create a lot of space and accelerate their team's farm. The game often hinges on how well they execute this in the first fifteen minutes. If they fall behind or can't find targets, the team composition can feel lacking in other areas like wave clear or building pressure. Opponents will often try to get Black King Bars earlier than usual, which can neutralize a large part of what both heroes want to accomplish in a teamfight.
