Pokémon Go offers a variety of different Pokémon that trainers can capture and train them regularly over time. Some of these Pokémon are stronger than others, making them ideal candidates for certain player-versus-player battles available in the game, like the Master League. There are no restrictions on what type of Pokemon you can use in this league, and one notable Pokemon that almost every trainer will see is Dialga.
Dialga is a Legendary Steel and Dragon-type Pokémon with a max CP of 4, Attack of 038, Defense of 275, and Stamina of 211. It is only weak for Fighting and Ground-type Pokémon, limiting your choices for defeat it. . You can expect to see Psychic, Flying, Water, and Grass-type Pokémon supporting it in the Master League. Your best approach to defeating a Dialga is to rely on tanks to withstand the onslaught of Pokémon attacks.
Dialga can also appear in five-star raids during rare events, and much of that still applies in those situations.
Pokémon to counter Dialga
The three best tanks capable of fighting Dialga are Groudon, Excadrill, and Rhyperior.

If you use one, you want it to know about mud splash, earthquakes, and sunlight. It's hard to go wrong with any of them in your group. However, he's weak on Grass, Ice, and Water, so you need to cover up those weaknesses if you're using Groudon, which can be a bit tricky to deal with, but not impossible once you've completed your squad. Master League.

He's not as powerful as Groudon, but he's a great runner-up, especially for those who don't have a Legendary Pokémon to cast. You want an Excadrill to know about mud slams, rock slides, and drill drops. An Excadrill that knows the Iron Head does more damage, but to fight Dialga you want to lean as much as possible on this Ground-type weakness.

Although stronger than Excadrill, he has significantly more weaknesses for Combat, Grass, Ground, Ice, Steel, and Water type moves. If you don't have any other powerful ground types, Rhyperior is a good choice, but you need to be prepared to defend it because your opponent can easily counter it with one of their other Pokémon choices. You want him to know how to hit, surf and quake. It would help to have a grounded or fighting-type rescue Pokémon when using Rhyperior, but overall make sure you can cover its variety of weaknesses, or you're in trouble.

These are good choices, not the best, but useful when you are in a rush or to have a backup option. The type of Pokémon you use to fight Dialga varies depending on your overall Pokémon roster, and you only have three options.
Dialga is a formidable opponent, and you expect to see more of it in the Pokémon Go Master League as more players compete against each other. There are dozens of Pokemon choices you can use, and there are no restrictions, so make sure you bring your best whenever you fight, as you only have 15 fights per day.
