Clockwerk

Have creep equilibrium close to your tower so you can run the opponents down for a while until they reach their tower.

Play in tree lines and prey on isolated heroes as Battery Assault does all the damage to the single hero.

Don't feed Power Cogs unnecessarily to opponents. Deny cogs as opponents start attacking them.

If an opponent can escape or fight you back in Power Cogs, don't trap him in the cogs but rather push him towards your team.

Use Rockets off cooldown to scout around the map and push out dangerous lanes.

In the teamfights, look to split opponents' team into two parts by placing cogs between their heroes.

Clockwerk is good at controlling debuff immune heroes as Hookshot stun pierces debuff immunity and Power Cogs act as barrier.

As position 4, you can take Power Cogs on level 1 to block your first creep wave inside them to bring the lane creeps closer to your tower.

Bring an Observer Ward to the lane to keep an eye on Clockwerk's aggressive movements.

Battery assault does a lot of damage. Keep distance from Clockwerk or share damage with allied units.

If you get trapped in Power Cogs don't panic. It takes two hits to destroy a cog.

Clockwerk has a great solo kill potential in early to midgame. Keep track of his movements.

Force Staff is great at moving you or an ally out of Power Cogs and out of Battery Assault range.

Clockwerk is great at contesting you at Roshan. Block his Hookshot path when you are about to finish Roshan.
