Stole this comp from someone I faced on ladder and made a slight tweak
All the Damage Reduction, Extra HP and Healing make this comp super resilient and survivable. The lead can blow up greens and blues on turn 1 very easily. Most of my turns I all-in my attacks on a unit I need to kill while looking to sustain my board to not lose a merc to crucial attacks.
Passives are broken. Yu’lon passive damage reduction, Nefarian passive healing, Voone passive Damage. Also, dont be afraid to use Voones Fire Breath, dealt 120 damage to a blue in 1 turn for me once and instantly won me the game!
