AI Overview: A Rocket Siege deck is defense first and offense second. You build a wall of buildings and cheap troops, save elixir, then fire Rocket at the tower when it also hits supporting troops. Rocket Cycle data in 2026 is thin. Mirror and Double Rocket are checked against the data. The numbers all trace back to the October 2026 card data.
Last Updated: October 2026
Key Points:
- A Rocket Siege deck builds defense first, so elixir can be saved for a guaranteed Rocket hit.
- There are two styles: Rocket Cycle with cheap defenders, and Double Rocket with Mirror.
- Pick at least two defensive buildings, one cheap (Tombstone, Cannon or Tesla) and one tanky (Bomb Tower or Inferno Tower).
- Fire Rocket only when it also hits supporting troops near the tower, unless the tower is nearly gone.
- In October 2026, RoyaleTracker lists Rocket Cycle at 0.18% usage, with top builds at 2.6 to 2.8 elixir and win rates from tiny samples.
How to Build a Rocket Siege Deck
You do not race. You make the rival work for every point of tower damage, and you save elixir for one clean Rocket.
| Step | Plan |
| 1. Add Rocket | The only win condition |
| 2. Pick a style | Rocket Cycle (cheap defense, fire Rocket often) or Double Rocket (Mirror) |
| 3. Buildings | At least two: one cheap, one tanky |
| 4. Fix weaknesses | Ask if the deck is weak to swarms or heavy troops, then balance |
| 5. Troops | Cheap, slow, defensive cards that stay on your side |
| 6. Spell | Optional: Zap, The Log or Arrows |
The short version: build a wall first, then add the Rocket. The catch: Rocket costs 6 elixir, so the cheap parts have to keep the average low. See the Rocket guide and the Rocket timing tips.
Rocket decks depend on tower damage, and tower damage has been cut on several spells this season. The negative effect: if Rocket takes a similar trim, the number of hits needed for a tower goes up, and a slow siege deck gets even slower.
Rocket Cycle vs Double Rocket
- Rocket Cycle: cheaper defense lets you cycle back to Rocket and keep removing the rival’s supports while blasting the tower.
- Double Rocket: Mirror joins the deck. It is more defensive, and it lets you clear the last 1,000 hitpoints of a tower in seconds.
The math: Mirror copies your last card for +1 elixir, so a Mirror Rocket costs 7. The catch: in October 2026, no printed Mirror list won 48% or more, and the best won 47.8% over 1,300 battles. The Double Rocket idea is fun, but the data does not back it. See the Mirror guide.
Rocket Cycle in 2026: RoyaleTracker lists it at 0.18% usage, with top builds at 2.6 to 2.8 elixir and win rates up to 82.5% from samples of 25 to 97 battles. Every printed deck runs at least two Evolutions or Heroes. Still unknown: the true win rate, because the samples are too small.
Picking Buildings and Troops
The old list of buildings is long: Cannon, Tombstone, Tesla, Mortar, Furnace, Goblin Hut, Inferno Tower, Bomb Tower, X-Bow and Barbarian Hut. The advice is simple. Take one cheap building and one tanky one that deals damage. Then fill the rest with slow, cheap defenders that stay on your side the longest.
- Cheap buildings: Tombstone, Cannon or Tesla. Tesla lifetime fell from 30 to 25 seconds on June 1.
- Tanky buildings: Bomb Tower (no 2026 change, best deck 70.1%) or Inferno Tower (best LogBait list 65.8%).
- Favorite troops: Skeletons, Ice Spirit, Ice Golem, Knight, Archers, Bomber, Mega Minion, Guards, Skeleton Army, Princess, Ice Wizard, Miner, Musketeer, Valkyrie, Baby Dragon, Inferno Dragon, Wizard, Witch and Bowler.
- Spell: Zap, The Log or Arrows, because a spell in every deck is usually a good idea.
What it means: avoid expensive or fast cards. They leave the zone before the Rocket is ready. The catch: the old list is from several years ago, so check each card’s cost and 2026 note before using it. See the Bomb Tower guide and the Inferno Tower guide.
As more cards get Evolutions and Heroes, cheap defenders gain stronger versions, and siege lists may rely on them more. The negative effect: Evolution and Hero slots are limited, so a siege list has to give up some value elsewhere to use them.
When to Fire the Rocket
Do not throw the Rocket as soon as it reaches your hand, unless the tower is nearly gone.
Wait until supporting troops are within range of the tower. The more expensive the troop, the better the target.
Best targets: Elixir Collector and Sparky next to a tower.
To get a support troop next to the tower, make sure the rival is committed to a lane. Let them take some health off your tower, but make them work for it, and spend less elixir than they do. Once they are committed, put up your defenses. Having two or three buildings at once is a great way to make the rival struggle while you save elixir.
The takeaway: patience is the whole deck. The catch: a delayed Rocket is a bet that the rival will not change lanes. See the Rocket and Tornado tricks and the Elixir Collector guide.
The Endgame: Close to 1,000 Hitpoints
When the rival’s tower is close to 1,000 hitpoints, things get tricky. They know they are about to lose it, so they do anything to stop you from having enough elixir to defend and fire Rocket. Keep calm. Defend while spending as little elixir as possible. This is where cheap defenders pay off.
The finish: if you play it right, throw the Rocket, sit back and watch it make its way to the tower. The catch: Rocket has a long flight time, so a rival who sees it coming can still react with a troop on the tower. Count the elixir before you fire.
If Rocket’s data stays this thin, Rocket Siege may remain a niche pick for fans of control play and not a ladder staple. The negative effect: players who pick a niche deck for fun can find that guides, counters and win rates are all hard to find.
