Juggernaut · physical (AD) damage
Trundle is a Juggernaut that deals physical (AD) damage and brings airborne, slow. Some of their lockdown (airborne) ignores tenacity, so you dodge it; you can't cleanse or Merc' through it. Below is Trundle's highest-win-rate build from high-elo games; open the counter-build tool to tune it against your specific enemy team.

When an enemy unit dies near Trundle, he heals for a percent of its maximum Health.

Trundle bites his opponent, dealing damage, briefly slowing and sapping some of their Attack Damage.

Trundle turns target location into his domain, gaining Attack Speed, Move Speed, and increased healing from all sources while on it.

Trundle creates an ice pillar at target location, becoming impassable terrain and slowing all nearby enemy units.

Trundle immediately steals a percent of his target's Health, Armor and Magic Resistance. Over the next 4 seconds the amount of Health, Armor, and Magic Resistance stolen is doubled.
