It spawns two single-target, melee, stronger, faster Barbarians with high hitpoints and very high damage.
An Elite Barbarians card costs 6 Elixir to deploy.
Since they spawn in pairs, they are useful for split pushing, with one Elite Barbarian down each lane.
Compared to the regular Barbarians, they have higher stats and many more offensive capabilities. However, they only come in 1 pair, while the Barbarians come in 2 pairs. Therefore, they do less overall damage than regular Barbarians and are less effective at defence due to their lower numbers. However, Elite Barbarians are less susceptible to splash damage (Fireball, Zap, Ice and Fire Spirits). Elite Barbarians also unlock in a higher arena (Royal Arena), which means that the Barbarians are much easier to obtain. They cost 1 more Elixir than the Barbarians.
Due to their very fast move speed the Elite Barbarians can be paired with other very fast units like the Hog Rider. They can also be used to push slower troops like the Valkyrie, which is also an excellent synergy; the Valkyrie takes out swarms while the Elite Barbarians take out the tankier troops.
Casting Rage on Elite Barbarians can be a deadly combo because the Elite Barbarians will hit faster and run faster which can demolish a tower in seconds, though it can result in a large negative elixir trade if it is countered. Because of this, pairing the Elite Barbarians with the Lumberjack may be just as effective since the Lumberjack's fast hit speed will help the Elite Barbarians take care of small swarms, and when the Lumberjack dies, his Rage effect will make the Elite Barbarians far more dangerous. However, this combo is vulnerable to swarm cards and air troops, so bring a spell like Zap or Arrows.
If the opponent is low on Elixir or you know that the opponent's counter for the Elite Barbarians is out of rotation, you can rush a lane with Elite Barbarians. Their very fast move speed allows them to reach the Crown Tower very quickly and gives little time for the opponent to react. However, it is advised to have a damaging spell ready since swarms will make short work of the Elite Barbarians.
A High-risk high reward move is to quickly send in Elite Barbarians at the start of a game as your opponent's counter card might not be in rotation and the Elite Barbarians will either deal extensive damage to the Crown Tower or put the opponent at an elixir disadvantage due to inadequate counters.
You can use a Rocket to completely destroy Elite Barbarians for a neutral Elixir trade. However, due to their very fast movement, coupled with the Rocket's slow travel time, it can be difficult and risky to use it successfully. Alternatively, you can use Lightning to cripple the Elite Barbarians and 1 supporting card.
Although Elite Barbarians have very high damage per second their health is only mediocre, so almost all swarms can counter it for a positive Elixir trade. An Ice Golem with any other high damage support card (e.g. Minions) can also easily take down the Elite Barbarians.
