Inquisitor's Ox

On an empty graveyard, this is a 2/5 wall and nothing else, which is precisely the design intent. Delirium cards of this stripe rewarded diversifying the graveyard rather than piling it high, and this Ox is the most defensive expression of that pattern: the upgrade is small, conditional, and entirely about holding ground. Switched on, it becomes a 3/5 with vigilance, a body that can attack without surrendering the block. Vigilance is the meaningful half of the reward; the extra point of power rarely changes which combats it survives, but swinging while keeping a five-toughness wall in reserve changes what an opponent can profitably do in return. Reaching the delirium threshold asks for enough variety in the yard that a creature, an instant, and a sorcery only get you partway, leaving the deck to supply the last type through fetching, milling, or a discarded artifact or enchantment. This is a mid-game stabilizer, not an early blocker: at four mana it arrives after the opening exchanges, meant to arrest the game while the delirium count assembles behind it and then quietly flip from wall to attacker without ever stopping being a wall. It also functions as a legibility marker for the delirium count, making the gap between an active and inactive threshold visible in combat. Nothing here is flashy, and that restraint is honest work: it exists to anchor a midrange shell that wants a diverse graveyard.
