Vona, Butcher of Magan

Repeatable removal stapled to a body is usually priced in mana; here it is priced in blood. The seven-life payment is a self-limiting clock that scales against your own resilience: the lifelink on the same card is not flavor, it is the resource loop that funds the ability, turning combat damage and incidental gain back into permanent destruction. The restriction that holds it in check is timing. Locking activation to your own turn strips out the ability to hold up an answer against an opponent's threats, so this is a proactive removal engine, not reactive interaction: you spend the life on your terms, on your turn, never as a surprise. Note the friction hidden in the tap symbol, too. Firing the ability leaves a tapped Vampire that can no longer block, and vigilance only saves the turns you attack before you activate. Unconditional destruction of any nonland permanent is some of the broadest removal a body can carry, but every activation taxes the life total that lifelink is trying to rebuild, so the engine only runs as fast as you can refill it. That tension is the whole design: removal-on-a-stick that wants to be a midrange linchpin but punishes the life total of any deck unwilling to win the attrition race it starts. Built as a Vampire Knight to grind, the loop belongs to any white-black shell willing to treat its life total as ammunition.
