She has purple combed hair, a musket and a metal helmet with a tiny crater on it.
The Musketeer can be used to back up higher hitpoint troops such as Giants. In fact, this is a deadly push as overlooking it can cause the player a three crown loss. This can easily be countered with a Skeleton Army or another swarm card.
As the Musketeer can target both air and ground troops, she is a powerful substitute to Archers, albeit at the price of a higher Elixir cost.
A Musketeer destroys Minions of equivalent level in two shots. It is not a good idea to counter a Minion Horde with a Musketeer unless a Crown Tower assists her.
She can counter Minions. This move is, however, a negative Elixir trade and the Musketeer will be left crippled.
If played as far away as possible, she can shut down the Mega Minion by herself due to its slow movement speed and mediocre health. This is a negative Elixir trade but the Musketeer can then be used to build a counter-push.
Her long range allows the Musketeer to help attack from a distance without engaging the defending troops. The Musketeer's long range (6 tiles) is effective against Crown Towers, as the King's Tower will be unable to target her if she is attacking a Princess Tower.
The Musketeer is an effective counter to the Cannon. Due to her long range, she can outrange the Cannon and destroy it unharmed. However, despite a Tesla having the same range as the Cannon, the Tesla's property of being invincible while underground forces the Musketeer to walk into range before targeting the Tesla.
The Musketeer is a good counter to the Baby Dragon, as she can destroy it on her own.
Due to being a single target card, cheap cards like Guards can take her out quickly if she is unaccompanied. Mini-tanks and high damage troops like the Knight or Mini P.E.K.K.A. also work well against her.
The Musketeer is extremely effective against the Balloon, as its slow movement speed enables her to land enough shots to destroy it before it reaches a Crown Tower. She must, however, be deployed before the Balloon crosses the bridge for this to work without the help of a Crown Tower.
A very powerful combo is the Hog Rider, the Musketeer, and the Valkyrie. The Musketeer is for protecting the Valkyrie and Hog Rider from air troops. The Valkyrie is for protecting the Musketeer and Hog Rider from swarms and the Hog Rider is used to tank for the Musketeer and Valkyrie. This strategy is commonly called the Trifecta for its combination of three troops.
Never ignore a Musketeer that is locked onto a Tower. Doing so will cause significant damage to the Tower.
If the player needs to pressure the other lane with the Musketeer, but also needs to defend the Tower on the other side, place her on the middle lane furthest from the side you need to defend.
Pairing her with the Ice Spirit can take down a Mini P.E.K.K.A. + Fire Spirits combo. The Ice Spirit takes out the Fire Spirits and freezes the Mini P.E.K.K.A. while the Musketeer finishes off the Mini P.E.K.K.A.
With the help of a Crown Tower, she can deal with the Valkyrie reasonably well. Vice versa, a Valkyrie assisted by a Crown Tower can deal with the Musketeer well.
The Musketeer card was released with Clash Royale's soft launch on 4/1/16.
