Skittering Horror
A 4/3 for three mana sat well above the curve when this kind of body was printed, and the penalty that paid for it is among the bluntest the early-era designers ever templated: the next creature spell you cast kills this one. The result inverts the basic instinct of a beatdown deck. Where a creature deck wants to flood the board, this one demands you stop cold, holding it until your hand has emptied of other bodies or playing it as the closer after every other threat has already resolved. Most "creatures with a downside" of the period attached something mild or symmetrical: a point of life loss, an upkeep tax, an inability to block. Here the cost is total and bound to the exact action the deck most wants to keep taking, which is what makes the sequencing puzzle real rather than cosmetic. The Phyrexian Horror flavor reads cleanly off the mechanic: a thing so volatile it cannot tolerate anything else sharing its side of the table. As a design it sits at the brutal end of the "free stats, ruinous string attached" school the late Urza-block sets leaned on, where the templating trusted players to locate the narrow window in which a wall of stats was worth surrendering everything that came after it.
