AI Overview: Card replacements in Clash Royale are swaps between two cards that do a similar job, like Fireball and Poison or Knight and Valkyrie. This guide keeps those pairs and updates costs, rarities and win rates, and it drops the old hit point and damage figures that no longer match the game. The numbers all trace back to the October 2026 card data.
Last Updated: October 2026
Key Points:
- Swap when the card is under-leveled, not unlocked, unfamiliar, or has the wrong cost or role.
- 17 pairs below: 12 from the first writer, 5 from the second.
- Best printed lists now favor Poison over Fireball, Knight over Valkyrie and Lumberjack over Mini P.E.K.K.A.
- Old hit points, damage and DPS figures are tournament-standard and out of date. They are not repeated.
When to Swap One Card for Another
The card is under-leveled. It is not unlocked. You are better at the other one. The effects are close. The level or rarity differs. The elixir cost differs. Or the other card fits the deck role better. The first writer based all of it on tournament-standard levels.
The simple test: if you do not own one of the cards, pick the other. If you own both, ask what the deck needs: more hit points, more damage, a cheaper cost or a special effect. Then check the numbers below.
The old comparisons use hit points, damage and DPS from a past balance. Those numbers have changed many times, so this page uses the card data that holds today: elixir cost, rarity, unlock arena and the best printed win rates from the site’s card guides. For the cards that are Legendary, see the Legendary swaps guide.
Supercell changes damage and hit speed every season, so a pair that was close in one patch may drift apart in the next. The negative effect: a swap that is fine today can turn into a bad choice with no warning, and players who learned the old numbers will not know.
Pairs 1 to 12: The First Writer
| Pair | Cost / rarity | What the data says now |
| Executioner vs Wizard | 5 Epic / 5 Rare | Executioner range 7.5 to 7 (Aug 4); Wizard damage 281 to 304 (Sep 8); best lists 59.9% (Evo) vs 51.3% (base) |
| Ice Wizard vs Electro Wizard | 3 / 4, both Legendary | Ice Wizard best 64.6%; Electro Wizard best 72.1% |
| Knight vs Valkyrie | 3 Common / 4 Rare | Knight best 67.1%; every printed Valkyrie base list is 47.8% or less |
| Goblin Gang vs Skeleton Army | 3 Common / 3 Epic | Gang best 62.9%; Army base best 55.6% |
| Miner vs Goblin Barrel | 3 Legendary / 3 Epic | Miner best 66.0%; Goblin Barrel best 65.4% |
| Skeletons vs Goblins | 1 / 2, both Common | Skeletons best 68.6%; Goblins best 59.9% |
| Electro Wizard vs Musketeer | 4 Legendary / 4 Rare | Electro Wizard 72.1%; Musketeer Hero 62.1% |
| Golem vs Giant | 8 Epic / 5 Rare | Golem best 68.7%; Giant best 71.6% |
| Mini P.E.K.K.A vs Lumberjack | 4 Rare / 4 Legendary | Mini P.E.K.K.A 60.6%; Lumberjack 72.3% (one of eight lists above 50%) |
| Fireball vs Poison | 4 Rare / 4 Epic | Fireball 60.4%; Poison 68.6% |
| Zap vs The Log | 2 Common / 2 Legendary | Crown Tower damage Zap 58 to 48, Log 41 to 35 (June 1); Log best 65.1% |
| Lightning vs Rocket | 6 Epic / 6 Rare | Lightning best 72.1% over 736 battles; Rocket Crown damage 371 to 342 |
Where the old call still holds: Skeletons are cheaper than Goblins, and Goblin Gang and Skeleton Army are still near-equals at 3 elixir. Mini P.E.K.K.A is the cheaper defender, and players call it as good as Lumberjack on defense.
Where it has moved: many players call Poison a slow cousin of Fireball, but its best list is now higher and the Crown Tower cuts hit both (Fireball 207 to 172 to 159, Poison 184 to 168). Lightning, which players call weak on defense, has the best printed list in its pair.
Open the card pages before you decide: the Fireball guide, Poison guide, Knight guide and Valkyrie guide list the exact deck samples.
The Valkyrie shows how a classic can fall off: her base lists are all 47.8% or less while her Evolution and Hero versions do well. The negative effect: a player who swaps in the base Valkyrie because she is a popular pick may take a weaker card than the one they left behind.
Pairs 13 to 17: The Second Writer
| Pair | Cost / rarity | What the data says now |
| X-Bow vs Mortar | 6 Epic / 4 Common | X-Bow best 62.7% (five of six above 57%); Mortar base lists 41.9% to 51.9%, Evo up to 69.7% |
| Skeletons vs Bats | 1 / 2, both Common | Skeletons best 68.6%; Bats best 48.2%, none of eight lists above 50% |
| Mirror vs Clone | Last card plus 1 / 3, both Epic | Mirror best 47.8%; Clone best 54.3% (Giant Skeleton in seven of eight lists) |
| Prince vs Dark Prince | 5 / 4, both Epic | Prince best 52.5%; Dark Prince best 57.9%, hit speed 1.3 to 1.4 (May 4) |
| Furnace vs Goblin Hut | 4 / 4, both Rare | Furnace best 72.1%; Goblin Hut best 72.1% (736 battles), the other six lists 41.8% to 46.1% |
Mortar over X-Bow for beginners: the second writer says Mortar is lower risk and easier to recover with. The data agrees on risk: Mortar’s base lists are all near or below 52%. The X-Bow is the stronger card in skilled hands.
Bats were not out yet. The second writer wrote his Skeletons vs Bats section before release and told readers to take it with a grain of salt. Today, Bats cost 2 and have no list above 50%.
Furnace vs Goblin Hut changed most. The Hut costs more and is overshadowed by Inferno Tower. Both are 4 elixir today. Only the Furnace and one Hut list do well. Furnace range dropped from 6 to 5.5 on June 1.
Clone and Mirror both unlock in Arena 15 and neither has a changed rule in 2026. For siege, see the siege decks guide and the Mortar guide.
Because Hero and Evolution versions get the best lists, base cards like Mortar and Valkyrie risk being left as the weaker twin. The negative effect: a swap guide that treats two base cards as equals can mislead players who do not own the special versions.
