Abaddon + Undying

Why this works

Picking Abaddon and Undying together commits the team to a very specific, slow-burn fighting style. Both heroes excel at being durable frontliners who wear down opponents over extended brawls. Abaddon's Aphotic Shield can keep a focused Undying alive, and a well-placed Tombstone creates chaos for Abaddon to exploit with his passive. The main issue is that their kits are redundant. They both offer sustain and disruption but bring no hard lockdown to the table. This shared weakness means they struggle to control mobile targets, who can often kite their combined slows until key spells like Flesh Golem expire.

The game plan is to force teamfights where this duo can grind the enemy down. With Borrowed Time making Abaddon unkillable and Tombstone swarming the fight, they can overwhelm teams who are forced to stand their ground. The problem is that many lineups can simply disengage or split the map, refusing to take these head-on brawls. Enemies with high burst can also pick off a key ally before the sustain from Abaddon and Undying can turn the tide. Success often depends more on the opponent's inability to counter this specific strategy than the inherent strength of the pairing.
