Bloodhall Priest

The whole card is built around a single condition that most decks treat as a liability: an empty hand. Hellbent has always been the harder side of black-red's design to pay off, because dumping your hand usually means you've run out of gas. This Vampire turns that emptiness into a recurring two-damage trigger that fires on both entry and every attack, which converts the topdeck war that black-red aggro tends to lose into one it can grind through: each fresh card drawn and spent reloads the threat rather than blunting it. The madness cost is what closes the loop and what makes the empty hand reachable in the first place. Pitch it to a rummaging or looting effect and it arrives off a discard at a discount, and the same engines that empty your hand to enable madness are exactly the ones that switch its ping on. That synergy is the reason it reads as more than a 4/4 with a conditional: the discard outlet that pays for it and the empty hand that arms it are the same deckbuilding decision. As a recurring point of reach that walks back from a deck's bad late game, it offers reach and a clock in one card, with the body large enough that opponents cannot simply race the trigger away.
