Strongarm Tactics

Symmetrical discard with the punishment riding on a deckbuilding assumption rather than a board state. Both players pitch a card, but the four-point life loss only catches whoever cannot spare a creature, so the effect is tuned to hurt spell-heavy hands and slide off creature-dense ones. That makes it a creature deck's tool dressed up as a discard spell: the caster wants bodies in hand to dodge the burn while the opponent sits clogged with noncreature cards and eats it. The symmetry, though, is only honest on the discard half. The life-loss half depends entirely on what each player is holding when it resolves, and if both are light on creatures, both take four, which collapses the asymmetry the card is built around and rules it out of the control shells most tempted by cheap two-mana disruption. It punishes the archetype, not the moment: against a deck full of creatures the discard still strips a card while the four life whiffs, and against a spell-heavy opponent the burn becomes the entire payload. The window where it works, caster aggressive with creatures and opponent caught without them, is narrow enough that it appeals to aggressive black builds rather than broadly. The real decision, which player the card actually hurts, is settled before it ever resolves, which is exactly what makes it more a deckbuilding declaration than a spell.
