Power Sink - Fourth Edition (Common)

Power Sink is an instant from Fourth Edition that counters a target spell unless its controller pays {X}. If they choose not to pay, they tap all lands with mana abilities and lose any unspent mana, which can disrupt their game plan significantly. This card is effective in control decks that want to apply pressure, forcing opponents to make tough choices while managing their resources. Available from Vault of Cards, a UK-based Magic: The Gathering store with fast delivery.
