Since its introduction in Season 74 “Fired Up“ during the August 2025 Update of Clash Royale, Furnace has taken a bold new direction, and evolution has found itself in many decks. Once known as a spawner building that passively chipped away at towers, Furnace is now a ground troop with ranged attacks.
Now the focus is on the evolution, which brings the best out of this new card. I’ll explore some of the best decks you can use to make the most of the new Furnace Evolution in Clash Royale.
Best Decks for the Furnace Evolution in Clash Royale
The Evolved Furnace retains the same base stats but introduces the ability Hot Spawns, dramatically increasing its Fire Spirit output. When attacking, it spawns Fire Spirits every 1.8 seconds, and each spirit deals 180% more damage.
The mechanism is overpowered by evolution, and the player needs to take advantage of it. My picks are as follows.
1. Furnace, Royal Giant, Royal Ghost, Fisherman, The Log, Skeletons, Electro Spirit, Lightning
Average Elixir Cost: 3.3
This deck is led by Royal Giant and supported by the Evolved Furnace. You’ll want to place Furnace at the back to start the cycle, using its frequent Fire Spirits to pressure early and support pushes later. It’s a faster spirit spawn that keeps the opponent constantly defending up troops and clear for the Royal Giant.
Fisherman provides pull utility to control tanks and redirect threats. Skeletons and Electro Spirit cycle quickly, allowing frequent rotations back to Furnace and RG. Lightning is your big spell, while Log is for chip damage. You can copy the deck here.
2. Furnace, Battle Ram, Mini PEKKA, Electro Wizard, Mother Witch, Dart Goblin, Arrows, Golden Knight
Average Elixir Cost: 3.8
This deck was something inspired by the PEKKA deck, but here we have a mini tank instead. The fast-spawning Fire Spirits force out responses or chip away at defending troops, letting Battle Ram connect more often. Meanwhile, Golden Knight shines in open-path rushes with his dashing ability.
Mini PEKKA is your main counter to tanks, while Mother Witch is to punish swarm-heavy decks. Dart Goblin and Arrows help in defence, especially behind your push. Punish elixir-heavy plays and keep applying pressure from Battle Ram. Test out the deck here.
3. Furnace, Knight, Graveyard, Berserker, Barbarian Barrel, Poison, Goblin Hut, Ice Spirit
Average Elixir Cost: 3.1
This is a slow control deck that builds up over time and wins through chip and surprise Graveyard pressure. The Evolved Furnace applies passive pressure and chips down the opponent’s towers and troops, while the Goblin Hut is a secondary spawner.
Knight is your anchor on defense, soaking up hits and pairing well with the Evolved Berserker, who can dish out major damage when triggered. The key here is patience: control tempo with both spawners, defend smartly, and use Graveyard when the opponent is low on counters. Copy the deck here.
