Vessel of Malignity

Discard has always carried a tempo problem: the spell that empties a hand is most useful early, when the opponent's hand is full, and worst late, when there is nothing left to take. This sidesteps that curve by storing its effect on the battlefield. It costs two mana to deploy and another two to fire, so it never advances your board, but the enchantment sits patiently until the opponent rebuilds, then strips two cards exactly when they have refueled. The exile clause is the sharper detail than the card count: cards taken this way leave the graveyard untouched, which shuts off the flashback, escape, and disturb recursion that ordinary discard quietly enables. Because the ability activates only at sorcery speed, it functions as a planned tax rather than an ambush on the stack, but the split into setup and payoff is what separates it from a slow Mind Rot. A patient deck can lay the vessel down on an idle turn and hold the activation for the moment the opponent topdecks back into the game, converting board-stall time into resource denial. As a piece of attrition tooling it trades raw speed for flexibility of timing, the inverse of most hand disruption, which front-loads everything onto a single cast.
