Vampire Lord - Night Attack
If you have another Vampire Lord in play, each other player with 4 or more cards in hand discards a card.
Choose one: Gain a card costing up to $5; or trash up to two cards from your hand.
Notes: Super fun prompt! Inspired by Heroes of Might and Magic III (which I have seen Donald X mention he is also a fan of).
I don’t see a simple and balanced way to do the Vampire Lord’s iconic and overpowered self-resurrecting life-drain attack. But Dominion's Vampire could certainly be simplified, and that’s what I’ve done here. The card attacks when you have more than one, like how Vampire Lords in Heroes III were more powerful when you had a bunch of them. Once you trigger it, the discard attack mirrors Soldier.
Edit: weakened the card a bit.
