Mana Leak⁣ - Double Masters 2022⁣ (Common)⁣ [58]

Mana Leak is an instant that counters a target spell unless its controller pays {3}. This makes it a flexible counterspell that can disrupt opponents' plans while remaining cost-effective at just {1}{U}. It's especially valuable in control decks that aim to maintain card advantage and keep the board state in their favour.
