Luna + Puck

Why this works

Setting up for a big Eclipse with Dream Coil can be unreliable. Puck's ultimate keeps targets in an area but doesn't force them to separate, which is what Luna needs for her ultimate to do maximum damage. Enemies can often clump up inside the Coil to spread the Eclipse beams, or a key target can simply use a BKB and walk out. While Puck provides lockdown, it's not the kind of hard, single-target stun that guarantees a kill for Luna. Both heroes also bring a lot of magic burst to a fight, which can be a problem if the enemy team builds an early Pipe of Insight or other magic resistance items.

This pairing often struggles to find its rhythm. Puck typically comes online first and wants to create space with aggressive ganks, but Luna is usually focused on farming and isn't the best carry to join early skirmishes. Later on, the team composition can feel fragile, lacking a sturdy front-liner that Luna needs to safely deal her physical damage with Moon Glaives. While Puck can initiate, they can't tank. This forces Luna to play from a riskier position and makes it harder for the team to control teamfights, even if they land a decent combo.
