What is the best deck to use in Arena 7 of Clash Royale?

In Arena 7 of Clash Royale, commonly known as "Royal Arena," a versatile deck that balances offense and defense while considering card availability can be highly effective. One such deck could include the Hog Rider for quick strikes, Valkyrie and Fireball for dealing with swarms and medium-sized troops, Musketeer for ranged support, the versatile Zap for crowd control and resetting Inferno Tower attacks, and the Giant for tanking damage. To address aerial threats, including Minions or Bats might prove useful, while adding in a building like Tombstone can help distract and counter enemy win conditions like the Royal Giant or Hog Rider. It is crucial to adapt one's deck based on the cards available and to continuously evolve strategies as one climbs the ranks in Clash Royale.
