## Description

Illustrated by Piotr Dura, this rare card functions as a dual-land source, producing either green or blue mana when tapped.

The card’s unique number and promo status distinguish it from the standard base checklist, making it a notable addition for those assembling comprehensive collections of the PM21 set code era. The dual color identity of green and blue supports a wide range of deck archetypes, though its primary value often lies in its foil finish and distinct promotional numbering. Temple of Mystery is a foil rare land from the 2020 Core Set 2021 Promos set that enters tapped and allows you to scry 1 upon entering the battlefield. The card’s straightforward land type and versatile mana output ensure it remains relevant for gameplay, while its foil treatment and promotional designation add collectible value for those curating their library of Magic: The Gathering cards.
