Sand Golem

A 3/3 for five generic mana is bad math by any era's standard, and this design knows it: the entire card lives in the discard clause. It is a piece of anti-discard technology from a period when black's hand attack (Mind Twist, Hymn to Tourach, Hypnotic Specter) was a real strategic axis, and the designers answered with a body that punishes the very plays meant to strip it from your hand. Force it into the graveyard with a discard effect and instead of losing the card you get it back as a 4/4. The trigger is narrow on purpose: it fires only when an opponent's spell or ability causes the discard, so you cannot loop it through your own rummaging or cycling, and it does nothing against milling, which moves cards from the library rather than from the hand. That restriction stops it from being a free recursion engine; the card is purely reactive, a deterrent priced as a body. The clause is also strictly a hand-attack answer, not a graveyard one: exile effects, library-stripping, and ordinary creature removal all walk right past it. The result is a strange, almost taunting design: a 4/4 the opponent only ever has to face if they choose to attack your hand, asking them to simply leave it alone and accept the dead card in your deck instead.
