Goblin Stadium (Arena 1)
“Tough melee fighter, deals area damage around her. Swarm or horde, no problem! She can take them all out with a few spins."
Valkyrie Clash Royale (Strategy)
This card wasn't played often in old times, but since its buff, it has been played more and more. Valkyrie is the only troop with melee attack in all directions (360 degrees). It's perfect against swarm troops and hordes. It replaces the Knight quite well, as for 1 extra elixir, will deal AOE damage and will be more tanky.
One of the best cards in the game, works in any deck on offense and defense, however it's not a game winner by itself.
Valkyrie shines on defense, she can counter many troops in clash royale such as Barbarians, Musketeer, Wizard, Witch and any swarm troops. One of the favourite uses is to place Valkyrie just after using Freeze in the middle of numerous troops and let her spin.
You should use her to defend against Skeletons, Goblins, Spear Goblins, Musketeer, Wizard, Ice Wizard, Princess, Witch, Dark Prince, Barbarians, Baby Dragon, and much more. Also, she is great on counter push.
It also performs well on offense. Some popular combos are the Valkyrie+Prince and Valkyrie+Hog Rider. In this combo, the Hog Rider pushes the Valkyrie to the tower while the Valkyrie tanks and kills small troops.
Some downsides are her average speed and her inability to target air units, allowing Minions to make quick work of her.
Mistakes to avoid: don't place it to stop the attacking tank as Valkyrie doesn't have high damage and doesn't work well in 1v1.
Extra Tip: Play her in the back. It's a good card to do that when at full elixir.
360 splash damage.
Valkyrie can tank for a push and it's great on defense.
It's not very tanky.
Weak in 1v1 melee.
