The use of DLC expansion in Pokemon Sword and Shield is a major advancement in the Pokemon series. Sword and Shield is the first major Pokemon game to use DLC to improve the base game. To enhance the fun of playing the game, you can Buy Shiny Pokemon from the PKMBuy store. Although the two DLC expansions have added new stories and mechanics, Sword and Shield's second DLC The Crown Tundra does a better job of introducing fascinating narratives and interesting new gameplay.

Pokemon Sword and Shield DLC both have added new areas to the overall Galar map. Although these two DLCs are meant to greatly improve the overall playability of Sword and Shield, The Isle of Armor only includes a short side story involving a local dojo, making the experience boring after finishing the storyline. 

Unlike The Isle of Armor, The Crown Tundra can increase the available game options in the base game. The overall narrative introduces NPCs related to the original storyline and greatly enhances the number of Legendary and Mythical Pokemon in Sword and Shield.  
 
Dynamax Adventures introduces a new way to participate in multiplayer games, while expanding the original concepts of Raid Dens and Max Raids, and includes a major post-game expansion of the Galarian Star Tournament. Long after the storyline of The Crown Tundra DLC ended, both mechanics were very attractive, allowing players to do more than just wander around the map after completion. 

The Crown Tundra DLC also adds new puzzles for players to eliminate, including a special mechanism for capturing Pokemon's Galarian Legendary Birds. Once found and released, these birds will split and spread throughout the Galer region. Players must go for the Wild Area, Map of The Isle of Armor, and search the map of The Crown Tundra to find each one. 

However, these Legendary Pokemon are not stationary while waiting for the player to find them. Instead, everyone needs the player to solve a short puzzle to intercept them. The same goes for the other Legendary Pokemon included in The Crown Tundra. These challenges allow players to immerse themselves in the hunt for these Pokemon, and when the Pokemon is finally caught, it will have a greater sense of accomplishment. 

Although The Crown Tundra helps expand the base game of Sword and Shield, there are still many aspects that can be improved by adding a third DLC. Buy Shiny Pokemon is very helpful in that time. Any one of the mechanics will expand the playability of Pokemon Sword and Shield and will remain relevant as new games continue to be released.
