Drain Power - Fourth Edition (Rare)

Drain Power is a blue sorcery from Fourth Edition that forces a target player to activate a mana ability of each land they control, leading to the loss of any unspent mana. This can disrupt an opponent’s plans by making them waste valuable resources, while you gain that mana for your own use. It's especially effective in control decks that aim to run your opponent out of options. However, it requires a clear window to target the right player, as it can backfire if they have no mana to lose.
