## Description

The Interplanar Brushwagg, designated as card number 79, emerged from the 2021 Magic: The Gathering Mystery Booster Playtest Cards set, offering collectors a glimpse into experimental game design. Created by artist John Penick, this rare creature card introduces the distinctive Interplanar mechanic, which separates the battlefield into two distinct zones: the standard plane and the interplanar battlefield. This design choice forces players to adapt their strategies, as creatures on the interplanar battlefield cannot be controlled by players in the same way as those on the main field.

As a green Creature — Brushwagg with a mana cost of {3}{G}, Interplanar Brushwagg brings significant power to the table with a 6/4 body and key keywords like vigilance and haste. Its most notable ability triggers whenever a player attacks with a creature that has four or greater power; in these instances, Interplanar Brushwagg automatically joins the assault against the targeted player or planeswalker. This mechanic makes the card a compelling subject for collectors interested in the evolution of Magic's rules systems and the innovative testing phases that shape future expansions.

For enthusiasts of the Magic: The Gathering trading card game, Mystery Booster Playtest Cards represent a unique niche. These cards are not part of standard commercial sets but serve as testing grounds for new mechanics and themes. Collecting this card allows hobbyists to own a piece of that developmental history. The card's identity as a rare playtest item adds to its appeal among those who track the progression of game design through Magic's various booster experiments. Whether you are building a collection of playtest rarities or focusing on unique creature types within the game, Interplanar Brushwagg stands out for its mechanical complexity and historical context within the 2021 release.
