3Clash Royale card guide
Skeleton Army is a cheap swarm that summons a big group of skeletons at once. It can melt huge single-target threats in seconds.
Drop it right on top of or in front of single-target cards like P.E.K.K.A, Giant, Prince or Hog Rider; the skeletons surround and destroy them. On offense, a Skeleton Army at the tower while your opponent's small spell is out of cycle can deal serious damage.
Cards that deal with it efficiently:

This card has an evolution. The evolution is active in your deck’s 1st (Evolution) or 3rd (Wild) slot. The Evolution slot unlocks at Arena 3, the Wild slot at Arena 10.
ElixirDeck automatically takes your unlocked evolutions and heroes into account: build your decks.
