Bellowing Saddlebrute

A 4/5 for four mana that sits above the historical curve for a black creature at this rarity; the body alone would be playable without the clause attached to it. What pays for that oversized frame is the life loss, and the structure of the clause is the interesting part. The cost is not waived by playing aggressively in general, but by having already turned a creature sideways this turn before the brute resolves. That sequencing requirement is the whole tension. Cast it on an empty board or on a turn you stumble, and you eat four life for a beater whose only relevant text is the trigger you just failed. Cast it after combat, when an attack has already happened, and the trigger checks the box and falls off, leaving a discounted wall that punishes nothing. The card rewards a board that was developing a turn ahead of it, which is precisely the tempo a black aggressive deck wants to maintain anyway. It is a clean study in conditional-cost design: the drawback only bites the decks that were never going to want it, and stays invisible to the decks built around it. The four life is steep enough to matter (a meaningful fraction of a starting total) without ever being prohibitive in the deck that meets the condition. The body does the rest of the talking.
