Snapfire + Undying

Why this works

Forcing fights around objectives can work out for this pair. Undying's Tombstone creates a chaotic area that's difficult for enemies to move through or focus targets in. If Snapfire layers Mortimer Kisses on top of that same area, enemies are stuck choosing between tanking the damage or trying to kill a Tombstone while being slowed and bombarded. The combination of slows and area damage makes any engagement messy for the other team, often letting your cores clean up while the enemy team is distracted and weakened.

This setup encourages playing together from the mid-game onward, looking for a brawl. Snapfire and Undying want to group up and force the enemy to react, ideally taking a tower or Roshan after a successful fight. Their strength is in that five-man clash where their spells overlap. The weakness is that they are somewhat predictable. A smart opponent will try to split the map to avoid these big fights, or use high burst damage to pick off Undying before he can place Tombstone. If the engagement doesn't happen on their terms, their combined impact is much lower.
