Unfortunately, this deck utilizes banned cards (Elder Entity Norden and Outer Entity Azathot), and can not be used in competitive play
Even if you dont choose to run them yourself, you can expect to see others doing so soon
There is a small tear in the cellophane on the top of the box
Take 1 "Aleister" monster from your Deck and either send it to the GY or banish it
You can also play dual-color decks if you use a dual-color Leader, which lets you mix the strategies (for example, Red/Green could blend aggro and re-stand combos, Blue/Purple could be a control deck with ramp elements, etc.)
The set includes fan-favorite Pokemon like Charizard, Blastoise, Venusaur, Pikachu, Mewtwo, Mew, and all the beloved Generation 1 Pokemon that started it all
