“Spawns an army of Skeletons. Meet Larry and his friends Harry, Terry, Gerry, Mary, etc.”
The Skeleton Army card is unlocked from the Training Camp (Tutorial). It spawns 15 single-target, melee Skeletons with very low hitpoints and damage. A Skeleton Army card costs 3 Elixir to deploy.
Due to their high numbers and overall high DPS, the Skeleton Army is very effective against single target enemy troops such as the P.E.K.K.A. or Giant.
Another benefit is the Skeleton Army's low cost of 3 Elixir, making it a very versatile card that can give you an Elixir advantage in almost any case.
They are very effective against building targeting troops such as Hog Riders if they are ignored.
Despite being incredibly susceptible to area damage, the Skeleton Army is capable of countering the Wizard, Witch, Bowler, Princess, Ice Wizard, and sometimes the Bomber at tournament standards. For this to work, the Skeleton Army must be placed directly on top of the unit to surround it and thus negate the splash damage.
Other swarm troops such as Barbarians and Minion Horde may be more favorable, as they have higher hitpoints compared to the Skeleton Army.
The Skeleton Army can force the enemy to use their splash spell, allowing you to deploy other swarms of low hitpoint troops to deal high damage, punishing the opponent. However, this may not be wise because it generally costs less Elixir to counter the Skeleton Army than to deploy it, resulting in a waste of Elixir.
Zap, The Log and Fire Spirits are very effective counters to the Skeleton Army that give a positive Elixir trade. Arrows and Bomber give a neutral Elixir trade. Using Poison or Fireball is a negative Elixir trade.
Splash units, despite their higher Elixir cost, will generally be at full health after eliminating the Skeleton Army and can be used in a counter push.
The Skeleton Army is not recommended to be used offensively, as they can be easily wiped out with spells such as Arrows.
Keep in mind that if the Skeleton Army manages to lock on to a Crown Tower, it will deal extremely high damage to or even destroy it.
The Skeleton Army is best paired with troops like the Witch, Prince, or any other troop with high damage. It can also be used to protect a P.E.K.K.A., Royal Giant, or another heavy troop when attacking.
The Skeleton Army can be used to great effect if the opponent has already used all their area damage cards.
The Skeleton Army can be used against most cards that deal death damage, as if a card has this stat, it is often too high to ignore.
A Skeleton Army can be used to counter another Skeleton Army with help from a Crown Tower.
Using a Rage on the Skeleton Army makes it a huge threat since they are already fast movers and attackers. Mirroring the Skeleton Army gives a huge numbers advantage. However, trying either of these strategies is very risky, as a splash unit or a spell can wipe it out for a positive Elixir trade. In double Elixir, the impact of failing this strategy is reduced because of the faster Elixir generation rate.
An Ice Golem is able to eliminate the entire Skeleton Army with its death damage at tournament standard. It can be used as an expendable counter to the Skeleton Army for a positive Elixir trade.
The Skeleton Army was released with Clash Royale's soft launch on 4/1/16.
