Furnace
Furnace overview
Card stats
Description
Spawns one Fire Spirit at a time while dealing damage with its special cauldron brew. It also makes great brick-oven pancakes.
Furnace battle strategy
At 4 elixir, Furnace plays as a Rare troop that targets air & ground. Released in 2016, it remains a reliable option for balancing offense and defense.
Opening plays and tempo
Lead with Furnace when you can float 4 elixir. It lets you test your opponent's responses without committing a full push.
Support combinations
Pair Furnace with spells or support troops that amplify a troop's pressure. Knockback, rage, or splash damage keep it on the board longer.
Defensive flip
Hold Furnace for air & ground pushes when you need a fast trade. Survive the defense, then stack it behind surviving units for a counterattack.
Synergies and deck ideas
Cheap cycle cards help you get back to Furnace whenever you need its toolkit in rotation.
Mix Furnace with win conditions that benefit from its support or let it pressure the opposite lane as a secondary win condition.
Playing around counters
Identify hard counters early
Watch for buildings, splash damage, or swarms that shut Furnace down. Force those answers out with spells or opposite-lane pressure.
Spell safety
Avoid stacking Furnace near your tower. High-damage spells punish clumped units, so stagger deployments to reduce risk.
Upgrade priorities
Track the damage and hit point breakpoints that matter at your ladder tier. Leveling Furnace so it survives common counter damage keeps it relevant.
