Product Overview

Description

The Golgari Signet, numbered 220 in the Modern Masters 2017 expansion, is an artifact card in the Magic: The Gathering trading card game. Released in 2017 under the set code MM3, this uncommon card serves as a foundational mana source for decks utilizing both black and green colors. With a mana value of 2 and a mana cost of {2}, it provides an efficient way to generate the specific colors required for complex strategies. As an artifact, the Golgari Signet functions by allowing the player to sacrifice one mana and tap the card to produce one black and one green mana. This dual-color output is particularly valuable in formats where mana acceleration is critical for playing powerful spells earlier in the game. The card’s design and mechanics reflect the Golgari swarm aesthetic, blending death and nature themes through its flavor text, which explores the duality of the natural cycle versus corruption. The Modern Masters 2017 set features Golgari Signet as card number 220. This artifact card has a mana value of 2 and allows its controller to add one black and one green mana. The card is printed with an uncommon rarity and bears the set code MM3.
