A planeswalker deck is a preconstructed theme deck designed by Wizards of the Coast as a starter product for beginning Magic players
Planeswalker Decks acquaint players who are interested in Magic with basic strategy, the game's settings, and characters, and include a premium foil Planeswalker card. According to Wizards of the Coast, Planeswalker Decks are the best first purchase for a new player, once they've learned the game through either Magic Duels or a Welcome Deck. But its features are meant to appeal to experienced players as well.
Core Set 2020 features 5 Planeswalker Decks for a cheaper price then previous sets. Each is built around a different Planeswalker. Those Planeswalkers are characters relevant to the set. Each Planeswalker Deck is a 60-card deck and is packaged with one booster pack from the Core Set 2019. They also contain a strategy insert and a Magic learn-to-play guide.
