Minions are a low health, swarm card and the cheapest flying unit you can get in Clash Royale. They target both air and ground units, making it a strong counter against ground targeting troops and buildings. Because of its cheap elixir cost, it is an advantage using it against pushing Barbarians, Giants, Valkyries, and buildings like Cannon and Bomb Tower as they all target only ground units.
One of the easiest way to counter Minions are by using Arrows and Zap spell. High level Minions can take three hits from the Arena Tower before killing one, making it more sturdier than Goblins.
