“Tough melee fighter, deals area damage around her. Swarm or horde, no problem! She can take them all out with a few spins.”
The Valkyrie card is unlocked from the Bone Pit (Arena 2). She is an area damage, melee troop with high hitpoints and moderate damage. A Valkyrie card costs 4 Elixir to deploy. She bears orange hair, a double-bladed battle axe, a brown fur coat, and attacks with a powerful whirl of her axe, damaging all the ground troops surrounding her in a 360-degree area of effect.
When using her to counter melee ground swarms, place her at a short distance instead of deploying her on top of the swarm. This minimizes the damage she will take, as she will not be hit while deploying.
In larger pushes, it may still be recommended to place her inside of the swarm, so that it is eliminated as quickly as possible.
She is extremely effective against most ranged low-hitpoint to medium-hitpoint troops. However, she must be placed right next to them so that she does not take unnecessary damage by having to first walk towards them.
The Valkyrie works well with the Mini P.E.K.K.A., as they are able to cover each others' main weaknesses. This combo, however, is very susceptible to air units, so be sure to have proper support.
Deploying the Valkyrie in front and then place the Mini P.E.K.K.A. directly behind her is the most effective method of attacking as the Valkyrie has more hitpoints and will be sped up by the Mini P.E.K.K.A. If the enemy deploys a swarm, the Valkyrie will eliminate them quickly. If the enemy deploys a tank, the Mini P.E.K.K.A. will walk around her and support her.
This combo can also be done with a Prince and a Valkyrie. It is more polarizing since the Prince has more health and his charge ability allows the combo to move even faster, but his damage per second is lower without his charge strike, and he costs more Elixir.
The Valkyrie also works extremely well with the Witch. Since they both do area damage, and the Witch can target air, they can take out most swarms, and the Witch's Skeletons can distract and attack single-target units and tanks like the P.E.K.K.A.
A cheaper alternative is to combine the Valkyrie with Goblins. While weak to area damage, the Goblins can also push the Valkyrie to the Crown Tower, and their combined damage will be enough to quickly bring it down if not countered.
Defensively, the Valkyrie is effective when played reactively. Instead of dropping preemptively against a push, it is better to wait for the support troops to cross the bridge and deploy her on them instead to distract and destroy the most threatening units.
The Valkyrie can be countered with cheap tanks or air cards. Additionally, well placed low damage troops, such as Ice Wizard, Spear Goblins, or Archers can also defeat the Valkyrie.
The Ice Golem will only counter the Valkyrie if it is kited into the other lane.
A very powerful combination is the Hog Rider, the Musketeer, and the Valkyrie. The Musketeer counters air cards, and works well with the other two troops in a counterpush. The Valkyrie can tank for the Hog on offense and the Musketeer on defense. This combo is often called the Trifecta.
However, this push can be stopped by Minion Horde, as the Musketeer is not capable of one-shotting Minions of equal level.
This push can also be crippled by the Bowler, as his knockback and damage slow down all three units.
This push can also be completely nullified by the Rocket for a +6 elixir trade.
The Valkyrie is a great counter to the Graveyard since she can quickly eliminate the skeletons with her 360-degree spin attack and can survive every damaging spell in the game.
If the opponent Freezes, the tower may take somewhat more damage, but the Valkyrie will still have a majority of her health left for a counterpush.
A Valkyrie can be used in tandem with a Balloon. Placing the Valkyrie in front of the Balloon makes her soak up the damage of the Crown Tower while dealing with smaller units that may target the Balloon, leaving the Balloon with a higher chance of reaching the tower. However, this combo is highly susceptible to air units and a building + tank combo.
The Valkyrie card was added with Clash Royale's soft launch on 4/1/16.
