Fight or Flight

Pacifism for half an army, paid once. Where most early white tax-and-restrict enchantments lock down a single creature, this one reaches into every attack an opponent declares and quietly halves it: split their board into two piles, and the controller may only swing with the pile they pick. The bisection scales with the threat. Against a go-wide board it can strand four or five attackers behind the line every combat; against a board of two or three meaningful creatures it forces a real choice, peeling the best attacker away from the rest. You are not removing damage, you are imposing a tax on the opponent's most efficient attack, and the wider their board, the deeper your cut. This is a repeatable combat deterrent that buys a defensive deck time rather than answering anything outright, closer in spirit to a Propaganda or Ghostly Prison effect than to a removal spell. The pile-splitting wording also dates it: hand-separating an opponent's creatures every one of their combats is the kind of fiddly, manual bookkeeping later design largely abandoned for cleaner static restrictions. What it offers is a soft, recurring brake on aggression that asks nothing of you after it resolves, scaling its grip to exactly how much the opponent commits to attacking.
