The Dart Goblin is best used behind a tank (for example, a Knight or an Ice Golem). The tank will sponge all damage for the Goblin, and coupled with the Dart Goblin's high hit speed, can quickly take down a Crown Tower. However, due to the Dart Goblin having low hitpoints, it can be taken down easily with The Log or Arrows.
The Dart Goblin's fast attack speed allows it to take care of small swarms quickly.
He can also easily counter a Graveyard with the help of the Arena Tower.
If there are buildings that are 4 tiles or less away from the river on the opponent's side, you can use the Dart Goblin to attack those buildings from your side of the arena.
A Dart Goblin can be used to out-range the Inferno Tower and Cannon, which can make him an excellent asset in battle to destroy your opponent's defenses and further your plans.
Note that the Tesla cannot be out-ranged because it is only vulnerable when attacking.
However, if the Tesla placement is 4 tiles from the river and 2 tiles from the Arena Tower, the player can place the Dart Goblin at the very edge of the bridge and he will ignore the Tesla and target the Arena Tower.
His range and speed allow him to easily run and get some chip damage to a Crown Tower or even finish it off if it has very low hitpoints. Even if the Dart Goblin has critical health, it will still get 3 shots off before dying and 5 shots at full health.
The Dart Goblin is excellent at pulling melee units towards the middle as due to his very long range, he can engage the unit while they approach him.
The Dart Goblin is a very effective counter to the Furnace; he can snipe the Furnace if placed 4 tiles away from the river and can one shot Fire Spirits of equal level (Tournament Standards).
The Dart Goblin can take down a Balloon with the help of a Crown Tower but it will not stop the Balloon's death damage from damaging the Crown Tower. This can be prevented by using an Ice Spirit.
