Wild Shard

“Defensive building. Whenever it's not zapping the enemy, the power of Electrickery is best kept grounded.”

The Tesla is a Common card that is unlocked from the Hog Mountain (Arena 10). It spawns a single-target, air-targeting, medium-ranged, building with high hitpoints and high damage. When there are no enemies within range, it retracts underground, making itself immune to all damage except for the Earthquake and the Freeze. A Tesla card costs 4 Elixir to deploy.

  • The Tesla can zap away some health from moderate hitpoint troops at a decent rate. It also deals moderate damage to higher hitpoint troops such as the Baby Dragon, and can also completely take out a Lava Hound and its Lava Pups without any assistance.
  • The Tesla can defeat any unit with less health than Minions in one shot if they are of the same Level, thus making it very effective against small hordes of low-hitpoint troops.
    • A Tesla can be a decent backup counter to a Graveyard. It attacks relatively fast, and has decent hitpoints to survive multiple attacks from the Skeletons, while also being unable to be pulled away by an incoming Tornado. Do not rely on it solely however.
  • When it retreats underground, the Tesla is invulnerable to any damage-dealing spell except for Earthquake, and cannot be targeted by any troops. However, the retreat is not instant, enabling quick troops like Spear Goblins to get a hit off before it goes underground. The retreat can also be stopped with a Freeze spell, enabling the player to attack the Tesla at leisure. The Tesla can also be frozen by a Freeze spell while underground, so it won't pop up when enemies are in range while the Freeze is active on it. This allows troops such as the Hog Rider to bypass a Tesla and head straight for the Crown Tower, as it can't be targeted while hidden underground.
    • Since the Tesla cannot be defeated while underground, its lifetime may discourage the opponent from attacking. Because of this, when it expires, it may incentivize the opponent to attack, so this is a good opportunity to prepare resistance against the post-Tesla response attack.
  • Although the Tesla has the same range as a Cannon, it can still target troops that would normally outrange it due to its ability to become invulnerable when not attacking, forcing them to come into its targeting range before they can target it. Thus, when using long-range units, the player should provoke the Tesla with another troop such as Skeletons first to prevent the long-range troops from wandering into its range and being destroyed.
  • The Tesla is very effective at distracting enemy building-targeting troops, such as the Giant and Hog Rider. By placing it in the middle of the player's part of the Arena (3 tiles from the bridge), the troops will target it instead of the Towers if it is not frozen. This placement will also pull regular troops to it.
    • If the player only wants the Tesla to pull building-targeting troops, they should place it 1 more tile away from the river. The Tesla will still attack any troops that come close enough to the Crown Towers, but it will not tank any hits for them. Alternatively, the player can place the Tesla 1 tile even deeper to pull the building-targeting troop even deeper, but this will result in support troops being out of range.
    • A Hog Rider or Ram Rider placed at the edges of the Arena will bypass a Tesla that is hidden whether it is placed 3 or 4 tiles from the river. A Tesla placed 2 tiles from the river will pull them to it, but this placement makes it very easy to snipe at the bridge, by using a swarm to force the Tesla to pop up and tank its shots while a ranged troop damages it down. Another method is to simply push them closer to the Tesla by deploying a grounded troop where it lands after it jumps across the edge, which will make Teslas placed 3 or 4 tiles away from the river pull them.
    • Against building-targeting troops which are placed in such a way that they are staggered towards the center of the Arena (e.g. a Golem placed behind the King's Tower), a Tesla reactively placed 4 tiles from the defending Crown Tower and 4 tiles away from the river can distract them. This is because the unit will walk closer to the inner side of the bridge (i.e. closer to the center of the Arena), rather than the center or the outside. Although this is somewhat situational, it is more effective at separating a tank from its support units than the above middle placement, as the tank will have to walk slightly farther, and the Tesla will not draw the attention of other grounded troops.
      • This placement also works against the Giant if he is placed directly on the bridge. His sight range is enough to allow him to travel towards the Tesla. However, this placement does not work against the Golem placed similarly, due to its lower sight range.
    • If the player suspects that the opponent has an Earthquake, Lightning, or Poison in their deck, they can place the Tesla 1 tile from the river. This will avoid the Earthquake hitting both the Crown Tower and the Tesla. However, this placement can be easily attacked by ranged troops, so use this placement if avoiding Crown Tower damage is a higher priority.
    • The Lava Hound's low sight range necessitates the Tesla being placed 5 tiles from the river and 1 tile from the Crown Tower in order to distract it. This position does not work against a Lava Hound placed on the furthest edge in the Arena; in this case, the Tesla has to be shifted a tile closer to the Princess Tower in order to distract the Lava Hound.
      • Against a LavaLoon push, it is most recommended to place the Tesla 3 tiles from the river and 2 tiles from the Crown Tower. This position allows it to distract the Balloon without distracting the Lava Hound. This forces them to separate and make addressing them easier afterwards. This placement also works against a lone Balloon or Skeleton Barrel.
    • If the player wants to pull troops closer to the King's Tower and further from the second Crown Tower after losing their first one, they should place the Tesla beside the King's Tower and 3 tiles from the top of the Arena. This will pull Giants towards in regardless on whether it was placed reactively or proactively. Against the Golem and Lava Hound, it only works if placed reactively. In order to avoid this, the player can place it 4 tiles from the top of the Arena instead, which will work better, as the Tesla will start attacking the Golem during its deploy time.
  • A Tesla can be interchanged with a Cannon or an Inferno Tower, depending on what the player is prioritizing in their deck. The Cannon costs 1 less Elixir, but doesn't target air troops, so it may be more efficient to have the Cannon if the player already has many air counters. The Inferno Tower costs 1 more Elixir and is extremely effective against high hitpoint units, but it is very volatile, being vulnerable to swarms and cards with a stun effect. If the player is not able to consistently eliminate these cards in a large push, the Tesla will allow the player to have more Elixir for other cards to damage down the support troops while also dealing more damage over its lifetime. The Inferno Tower is also a Rare card, so it will be harder to level up for use on the ladder.
  • Unlike most other buildings, the Tesla takes up a 2x2 space as opposed to a 3×3 space. This means that it can fit in the gap between a Crown Tower and the edge of the Arena. This is a good idea to do to limit where the Miner can be placed next to the Tower. This placement is also good for when the player wants to defend the second Crown Tower once their other Crown Tower has been destroyed.
  • Its versatility against most types of troops makes it a good card for supporting siege buildings like X-Bow or Mortar from the player's side of the Arena. Generally, the Tesla should be placed beside and slightly behind the siege card so that it is protected by them while it damages down enemy units.
    • On the contrary, it is also decent against an X-Bow or Mortar. Its decent Elixir cost and hitpoints will allow it to tank a notable amount of attacks, and its high damage and fast hitspeed will let it dish out plenty of hits to the building or any of its support cards.
  • The Tesla, despite having an electric theme and attack, does not stun, and thus cannot reset the Inferno Tower, Inferno Dragon's attack or the Sparky's charge. It can distract and eliminate the Inferno Dragon relatively easily but will get instantly destroyed by a Sparky.
  • The Tesla is a good response to a Princess placed at the bridge. Its underground mechanic prevents spell responses against it and it may also discourage the opponent from placing the Princess to attack the Crown Tower.

  • The card's name is a reference to Nikola Tesla, a famous scientist known for working with electricity. It is based on one of his inventions, the Tesla coil which wirelessly transmits electricity to the destination; the way tesla coil transmits electricity appears similar to how the Tesla attacks.
