Convolute⁣ - Core 2020⁣ (Common)⁣ [55]

Convolute is a blue instant from Core Set 2020 that counters target spells unless their controller pays four mana. This can disrupt opponents' key plays while potentially forcing them to overextend their resources. It's a solid choice for control decks that aim to control the game by stalling threats. Available from Vault of Cards, a UK-based Magic: The Gathering store with fast delivery.
