What Tesla Does
The short version: Tesla is a 4-elixir Common building that defends with electric shocks. RoyaleTracker’s card text calls it a defensive building and says that when it is not zapping the enemy, the power of Electrickery is best kept grounded. It unlocks in Hog Mountain (Arena 10).
It is a defensive tower you place in front of your own Crown Tower. It shocks anything that comes close, and it disappears after a time limit.
What changed: SeeMeta lists two. On June 1, the lifetime went from 30 to 25 seconds (-16.7%) and hitpoints from 1,152 to 1,182 (+2.6%). On May 4, the Evolution’s pulse damage went from 174 to 148 (-14.9%). What it means: the building lives a little shorter, and the Evolution hits a little softer.
| Stat | Value |
| Elixir cost | 4 |
| Rarity | Common |
| Type | Building (defensive) |
| Unlocks | Hog Mountain (Arena 10) |
| Evolution / Hero | Evolution, no Hero |
| Last change | June 1, 2026 (SeeMeta) |
Tesla still wins in four of the eight printed lists after the lifetime cut. If Supercell trims it again, a faster timer is the likely lever. The negative effect: a defensive building that expires sooner leaves the tower open to the next push.
Best Tesla Decks Right Now
RoyaleTracker printed eight Tesla decks. The best, an Evo Skeleton Army list with Evo Goblin Barrel and Hero Valkyrie, won 64.2% over 1,800 battles. Two more won 63.6% and 62.9%, and a Sparky and Clone list won 54.3%. The other four won between 43.3% and 48.0%.
The pattern: the three best lists average between 2.8 and 2.9 elixir. The four lists at 3.8 or more that do not run Sparky and Clone won under 48.1%. None of the eight lists runs Evo Tesla. What it means: Tesla wins in cheap decks, not in heavy ones.
| Build | Cards | Avg elixir | Win rate (sample) |
| Evo Skeleton Army, Evo Goblin Barrel and Hero Valkyrie | 2.9 | 64.2% (1.8k battles) | |
| Evo Valkyrie, Evo Firecracker and Earthquake | 2.8 | 63.6% (2.2k battles) | |
| Evo Goblin Drill, Evo Giant Snowball and Hero Knight | 2.9 | 62.9% (707 battles) | |
| Evo Skeleton Army, Giant Skeleton and Sparky | 4.1 | 54.3% (1.5k battles) | |
| Valkyrie, Lumberjack and Mega Knight | 3.8 | 48.0% (830 battles) | |
| Sparky, Electro Wizard and Electro Giant | 4.1 | 45.6% (2.0k battles) | |
| Evo Witch, Giant and Miner | 4.0 | 44.7% (1.1k battles) | |
| Evo Witch, Evo Lumberjack and Fisherman | 4.0 | 43.3% (644 battles) |
Try it yourself: open the Clash Royale Deck Builder with the Evo Witch and Giant build in the table above, 44.7% in the tracker sample (1,100 battles), already loaded. It averages 4.0 elixir and is the only Tesla list with Giant. Swap Furnace or Goblin Hut for a cheaper card to lower the cost.
How to Play Tesla
- Place it in front of your tower. It pulls a Hog Rider or Ram Rider off its path.
- Play it before the push arrives. A fresh Tesla has the longest time to work.
- Keep the deck cheap. The three best lists average under 3 elixir.
- Pair it with small cyclers. Skeletons, Ice Spirit and Fire Spirit are in the winning lists.
- Do not drop it too early. With a 25-second life, it expires if the enemy waits.
The move: next game, hold Tesla until the enemy commits a win condition, then place it so the tower and the building shoot together.
Evo Tesla lost pulse damage on May 4, and no list on this page runs it, although a Giant Skeleton list and an X-Bow list on other pages do. If it spreads to more lists, another look at its numbers is likely. The negative effect: a building that lasts a shorter time and hits softer can leave the tower open.
How to Counter Tesla
- Wait it out: it has a 25-second life, so a patient push beats it.
- Spells: Fireball or Rocket kill it, but the trade costs more than it does.
- Out-range it: Mortar, X-Bow or a spell from outside its range.
- Use a swarm: Skeleton Army or Goblin Gang spreads the damage.
The catch: do not send a single tank into a fresh Tesla. It deals damage to one target at a time.
Is Tesla Worth Using Now?
Is it worth it? Yes, in a cheap, cycle-style deck. Four lists won over 50%. The catch: the four heavier lists that do not run Sparky and Clone won 43.3% to 48.0%.
What to remember: Tesla is a cheap building that wins by trading well, not by lasting.
Poison is in the 62.9% list and lost tower damage on June 1, from 184 to 168, the same day as the Tesla lifetime cut. If both hold, that list shows how much a low-cost deck can absorb. The negative effect: a list with 707 battles may not hold up once more players copy it.
Go deeper: For the cards in its best lists, read the Skeleton Army guide, the Sparky guide and the Goblin Drill guide. Building something similar? The Clash Royale Deck Builder tracks the average cost for you.
