You can speed up the number of new packs you can open by using the free giveaways developers have provided.

Since Pokémon TCG Pocket launched, a number of meta decks have emerged. This includes decks based on Mewtwo ex, Pikachu ex, and Starmie ex cards, which have dominated the game so far. However, the new Mythical Island set spices this up. New game-changing abilities give different Pokémon types more play, while other items and cards bring new elements into matches that need to be considered by players. Here are the top 10 best new cards introduced in the Mythical Island expansion that you should use in your decks.

10 Golem

Giving Fighting Pokémon A Chance

Fighting-type Pokémon haven't served much purpose so far in Pokémon TCG Pocket, but a couple of new cards in Mythical Island make them viable. Golem's new card is a powerhouse both on offense and on defense. His 160 HP means it will be able to take at least one attack from almost all opposing Pokémon, whilst its own attack, Guard Press, can do 120 damage. It also reduces the opponent's next attack by 30, meaning it can take over battles if Golem comes into the active spot at the right time.

9 Pokémon Flute

The Most Powerful Item Yet

The biggest game-changing item in the new expansion is Pokémon Flute. It allows you to bring a new basic Pokémon from your opponent's deck onto the bench. While the majority of items are useful in set situations, only a handful are regularly used in the most popular decks. Combining this with Sabrina to then bring a Pokémon into the active spot can pick up a crucial point at any stage of a tight game.

8 Leaf

Another Trainer That Can Cause Problems

Several useful Trainer er cards have been added alongside the powerhouses of Misty and Blaine, and in the right deck, Leaf can make all the difference in battles. If you are playing decks with several Pokémon that require high retreat costs, Leaf can allow a quick change that otherwise would not be possible.

Aside from Leaf, players need to use the X-Speed card, which reduces the retreat cost by one.

Leaf is especially useful if you have an ex card in your active spot but can't afford for it to be potentially KO'd, as many of them have at least a two-retreat cost.

7 Aerodactyl ex

Stopping Evolutions In Their Tracks

As already mentioned, Fighting-type cards haven't been very effective so far in Pokémon TCG Pocket, but Aerodactyl ex is a powerful option that can counter some key decks. His attack on Land Crush causes 80 damage and only costs 2 energy cards, making it a quick attacker. However, its ability, Primeval Law, is where it comes into its own. It stops opponents from evolving their active Pokémon, which could be powerful against certain decks that need time to build.

6 Gyarados ex

Another Dominate Water Type

Water-type cards have been one of the most dominant in Pokémon TCG Pocket, especially due to the overpowered Misty er card, which can give players a large amount of water energy right off the bat. While not needing any more powerful cards, Gyarados ex is just that.

It has one of the highest HPs of any Pokémon currently available at 180, meaning only a couple of opponents can knock it out in one go. On top of that, its attack deals 140 damage, so if you can keep it on your bench long enough to collect four energy cards, it can win matches very quickly.

5 Pidgeot ex

Flying In For The Quick Knockouts

Pidgeot decks challenged the meta in the first set of cards and were one of the most underrated. However, its new ex version is even stronger. Like many of the other ex cards, it has a huge HP as well as a powerful attack. It does a base 80 damage, but if your opponent has a full bench, it will deal 140 damage for just three energy cards. It will only work in certain decks, but it is a great finisher if you have cards that can quickly power it up.

4 Mew ex

The Original Hidden Creature Can Still Dominate

Mew was available as a hidden card following the launch of the game. However, it is only its ex version which is set to have an impact in the meta, but what an impact it has. While only having 130 HP, which is low compared to most ex cards, it has a Genome Hacking attack, which can potentially take out anyone in one go.

Only by costing three energy points can you pick one of the opponents' attacks to use against it. If brought off the bench at the right time, it can take out the other meta Pokémon, such as Mewtwo and Celebi, in one strike.

3 Vaporeon

Even More Water Provided

Misty has helped Water-type decks dominate already, but Vaporeon has the potential to make them even more of a force. If you evolve an Eevee into it, Vaporeon has the ability "Wash Out."

Wash Out can be performed by Vaporeon as soon as it is on the bench; it does not need to be in the active spot.

Wash Out allows you to move any water energy cards between your Pokémon that are active and on your bench. This can be used to quickly switch all the energy onto your most powerful water- types, such as Articuno ex or Gyrados ex, setting them up for their main attacks.

2 Celebi ex

The Real Mythical Pokémon

Of all of the new additions in the Mythical Island expansion, Celebi ex is by far the strongest, and when set up correctly, it appears to be unstoppable. Its attack, Powerful Bloom, only costs two energy cards at first. Potentially dealing 100 damage depending on your coin toss luck.

However, with every additional card that is attached to Celebi, you get another coin flip. This means that if you have four energy on it, it can potentially do 200 damage in one hit. This would be enough to take out any Pokémon. In addition, its 130 HP prevents it from being able to be KO'd in one go apart from against the very elite opposition Pokémon.

1 Serperior

The Ultimate Energy Provider

Most Pokémon you want to include in your decks are attackers with powerful offensive moves. However, cards can be crucial to have any chance of setting up those attackers. Step forward, Serperior. While it is a stage two evolution, once evolved, Serperior can be used in any grass deck to run over opposition teams. Its ability means that any grass energy card attached to a grass Pokémon is worth double.

So, Celebi ex would only need one energy card to attack, and with just two energy cards, it could potentially deal with 200 damage. This also works for previous powerhouses such as Venusaur ex. It does take a few turns to set Serperior up through evolutions, but once it is, it can almost guarantee victory.

The new Mythical Island expansion offers another reason for gamers to keep playing PokémonT CG Pocket, and you should go out of your way to collect these ten cards that can make a difference to any deck.
