The Ruinous Powers
Most cards that let you play off an opponent's deck treat the theft as the whole reward: you spend the mana, you keep the card, everyone moves on. This one turns the exiled card into a two-sided weapon. You still pay full freight for what you steal (the mana-of-any-color clause is what makes the ripped card castable rather than a color-locked dead draw), but casting it also costs its owner life equal to its mana value. So the same spell hits twice: once as a resource you now command, once as a life total ticking down across the table, with no life coming back to you. The randomness is the friction that keeps this from being a clean tutor. The upkeep trigger points at no one in particular, the exile happens before you know what you will get, and the chosen player is picked at random each turn. It fires once on each of your turns regardless of how crowded the table is, which means the engine's ceiling comes from what a single opponent's top card offers, not from the number of opponents you could rob. It sits in the black-red lineage of engines that convert other people's resources into your advantage, but where those usually stop at simply letting you cast the card, this one adds a bleed the victim pays for the privilege of losing it. The larger the spell you rip, the deeper the wound in the person you took it from.
