## Description

The Beast Within card from the Commander 2021 set (C21 #186) serves as an uncommon green instant within the Magic: The Gathering trading card game. Designed for the Commander format, this card number 186 offers a specific interaction that balances board control with resource generation. The card requires two generic mana and one green mana to cast, resulting in a mana value of three. As a single-color green spell, its color identity remains strictly green, allowing it to fit into decks led by green commanders. The gameplay effect allows the player to target any permanent on the battlefield and destroy it. Instead of removing the permanent without consequence, the controller of the destroyed permanent must create a 3/3 green Beast creature token. This mechanic provides a strategic trade-off, offering removal while simultaneously placing a creature under the opponent's control. The card's effect destroys a target permanent and creates a 3/3 green Beast creature token for its controller. First printed in earlier sets, this iteration from Commander 2021 features artwork by Jesper Ejsing. The card includes flavor text that adds narrative depth, quoting Euphemia, a Nexus watcher, on the nature of monsters and civilization. This card is part of the Commander 2021 set and costs {2}{G} to cast. The card is numbered 186 in the Commander 2021 set.
