## Description

The 2018 Guilds of Ravnica Promos release of Firemind's Research is a rare foil enchantment card featuring artwork by Grzegorz Rutkowski. This Magic: The Gathering trading card game card carries the card number 171s and utilizes the PGRN set code to identify its specific promotional origin. As an enchantment with a mana cost of {U}{R} and a mana value of 2, it belongs to the blue and red color identities. The card’s mechanics allow players to leverage their spellcasting for strategic advantage. Whenever an instant or sorcery spell is cast, a charge counter is placed on Firemind's Research. These counters unlock two distinct effects: removing two counters for {1}{U} allows the player to draw a card, while removing five counters for {1}{R} deals 5 damage to any target. This design supports flexible gameplay strategies that adapt to the flow of the match. The 2018 Guilds of Ravnica Promos release includes Firemind's Research as a foil rare enchantment. The foil treatment on this 171s variant adds a distinct texture and sheen that differentiates it from non-promo printings. Firemind's Research is a {U}{R} enchantment that puts charge counters on itself when you cast instant or sorcery spells. The combination of the powerful enchantment type and the sought-after foil promo finish makes it a notable addition to any Magic: The Gathering collection.
