Omniknight counterpicks: who to choose against this hero in Dota 2

Omniknight is a melee strength hero, most often acting in a support role. He has strong abilities that will allow him to effectively support his team in combat.

A good choice against Omniknight will be heroes that:

• Can dispel positive effects from enemies
• Reduce healing and health regeneration or burn mana.
• Have good control

Some of the best heroes against Omniknight:

• Shadow Demon - Demonic Purge not only dispel buffs when applied, but will not allow them to be refreshed while under the effect of the ability, and Disruption is a good save and control against Omniknight.
• Ancient Apparition - Ice Blast is extremely effective against Omniknight, as the victim cannot heal or regenerate, and Ice Blast lasts much longer than Repel and Guardian Angel, making it extremely difficult for Omniknight to help his allies in a fight against Ancient Apparition.
