Wraith King + Templar Assassin

Why this works

Stacking armor against this pair is an obvious and effective strategy. Templar Assassin wants to explode a single target with a Meld strike, but Wraith King offers little to enable that beyond his one stun. Their damage profiles are almost entirely physical, so an opponent with an early Ghost Scepter or Platemail can feel surprisingly safe. Wraith King is a durable frontliner, but he doesn't bring the lockdown or magical damage needed to open up targets for TA. Reincarnation forces the enemy to fight him twice, but it doesn't create the kind of chaos that a fragile hero like Templar Assassin needs to get a second combo off safely.

This puts all the pressure on Templar Assassin to dominate her lane and control the map's tempo early. If she gets a good start, she can create space for Wraith King to farm. If she falls behind, the game becomes very difficult. They both want to farm similar areas to hit their core item timings, which can starve the map for your own team. Their plan is to out-farm the enemy and win with overwhelming physical damage late, but they don't help each other get there. It’s a greedy approach that is easily punished by early aggression.
