Bloodsworn Squire // Bloodsworn Knight

The activated ability reads like a survival mechanism and works like a fuel gauge. Paying to make the Squire indestructible and tap it looks defensive: it eats a removal spell, sits back, waits. But the discard clause is quietly loading the yard, and each activation that pitches a creature card pushes toward the transform threshold. Cross four creature cards in the graveyard and the flip happens on that same activation, turning a stalled 3/3 into a Knight whose body scales with everything you've been throwing away.

That coupling is the whole design conceit: the cost of protecting the front side is the payment that unlocks the back. Most transform creatures gate the flip behind a passive condition (day and night, casting spells, a damage clock) and let it happen on its own schedule. Here the flip is bound to the same button you press to stay alive, so the player is never choosing between defense and progress; they are the same action. Once flipped, the Knight keeps the indestructibility outlet but drops the transform check, because it has nowhere left to go, and it inherits the graveyard as a scaling engine rather than a threshold to clear. It rewards the kind of black deck that treats its graveyard as inventory: discard payoffs, self-mill, creatures that want to die and come back. The Squire is the meter for how committed that plan already is.
