Mercurial Geists⁣ - Eldritch Moon⁣ (Uncommon)⁣ [186]

Mercurial Geists is a 1/3 Spirit from Eldritch Moon with flying that gains +3/+0 until end of turn whenever you cast an instant or sorcery spell. This ability allows it to deal significant damage in a single turn, making it a strong choice for spell-heavy decks that focus on tempo and quick strikes. However, being a creature with low toughness means it can be easily removed, so it's best used in combination with protective spells or in a strategy that can quickly capitalise on its temporary power boost. Available from Vault of Cards, a UK-based Magic: The Gathering store with fast delivery.
