Tusk/Counters

Bad against...

 * Tusk has low mana pool, making Anti-Mage the best counter for him through out Mana Break. Snowball is uneffective against Blink.


 * Riki's Cloak and Dagger can dodge the Snowball stun. Smoke Screen also increases the difficulty of landing a Warlus Punch!


 * If Tusk is not careful, upon being released from his Snowball he could find himself amongst mines.


 * Boulder Smash can return Tusk after his initiation. Geomagnetic Grip also removed Tusk's escape with his Snowball.


 * Glimpse can return Tusk to where he was after using Snowball.

Others

 * Broodmother
 * Axe
 * Entry

Items

 * Linken's Sphere prevent be targeted from Snowball.
 * Lotus Orb creates a second Snowball on the Snowball target.
 * Blade Mail is abysmal to Tusk as it returns the physical critical of Walrus Punch!

Good against...

 * Pugna's low hp and reliance on channeled abilities make him very vulnerable to Tusk, although Pugna can win in a straight up 1v1 later in the game.


 * Viper Strike can be countered through Snowball, wasting Viper's mana through his ultimate, and he's more likely prone to the crit of Walrus PUNCH!


 * Shadow Fiend is immobile and has low base hp, making him easy prey in a gank.


 * Slark relies on quickly picking off your allies, and Tusk's snowball, which can pass through the leash of Slark's pounce, can help save them while also stunning Slark. In addition, the attack and move speed slow from Tusk's sigil cannot be purged off, making Slark weaker in fights.


 * His Walrus Punch! makes LC loses Duel easily, especially when she doesn't have Blade Mail.

Others

 * Ember Spirit
 * Linken's Sphere
 * Entry

Works well with...

 * Snowballing towards an enemy while Lifestealer has infested you could result in an easy kill with your and 's burst damage followed by Lifestealer's autoattacks.
 * You also can trap your enemies with to make them unable to escape from Lifestealer's attacks.


 * Snowballing with Axe could help him line up his while the enemies are stunned by your snowball.


 * Snowballing into the enemy with Tidehunter could help him easily line his.


 * sing your snowball to gank an enemy for free duel damage is really easy with your and ' high burst damage.

Juggernaut
 * can trap an enemy for a full-duration blade fury by Juggernaut. It works especially well during the early game when heroes have relatively low hit points.

Others

 * Timbersaw's and Tusk's  slows stack, resulting in effective reduction of enemy MS.
 * Snowball Techies makes Suicide Squad Attack! best effective.
