## Description

Tekuthal, Inquiry Dominus is a Legendary Creature — Phyrexian Horror from the 2023 Phyrexia: All Will Be One Promos set, designated as card number 71s. With a mana cost of {2}{U}{U} and a power/toughness of 3/5, this Magic: The Gathering card offers distinct gameplay capabilities centered around counter manipulation. The card features a foil finish and is illustrated by Martin de Diego Sádaba, contributing to its visual identity within the PONE set code release. The card’s rules text provides two primary abilities that define its utility. First, it possesses Flying, allowing it to bypass ground-based blockers. Second, it modifies the proliferate mechanic: if you would proliferate, you proliferate twice instead. This doubling effect can significantly accelerate counter placement on artifacts, creatures, and planeswalkers during gameplay. Additionally, Tekuthal offers a conditional ability that requires paying {1}{U/P}{U/P} and removing three counters from among other artifacts, creatures, and planeswalkers you control. In exchange, you may put an indestructible counter on Tekuthal. The {U/P} symbol allows players to pay either {U} or 2 life, providing flexibility in resource management. As a Mythic Rare, this promo card holds a specific place in the collector’s landscape for Magic: The Gathering enthusiasts. The combination of its legendary status, foil treatment, and unique mechanical design makes it a notable entry for those interested in the Phyrexian theme. Collectors looking to complete sets or acquire specific promo variants often target this card due to its distinct number and rarity tier. The 2023 release date places it within a recent era of Magic: The Gathering product lines, making it relevant for modern collections.
