In 2020, Magic: The Gathering received a new game expansion called Magic Core 2021, or shortly M21. This expansion has 5 deck sets, all containing cards of a single color. The color chosen for the Garruk deck is green. What's more, these decks are focused around a planeswalker, who borrows its name to the deck.
Garruk, Savage Herald, is the planeswalker of this deck. He comes with 26 Creatures, 5 Instants, 2 Enchantments, and 1 Sorcery. Let's not forget that all these decks contain 25 Lands each. It's easy to guess that Forrests are the Lands of choice for this deck.
The Garruk deck has 4 exclusive cards: Garruk, Savage Herald, Garruk's Warsteed, Predatory Wurm, and Wildwood Patrol. For collectors, their numbers are 336 through 339.
