Soldevi Golem
A 5/3 for four mana that pays for an aggressive stat line with a tax written directly into its untap step: it stays tapped unless you spend each upkeep handing an opponent back one of their tapped creatures. The cost is paid in tempo you give the other side, and the untap clause is the half worth studying. Most "doesn't untap" creatures from this era simply sat there until you found an external untapper; here the card builds its own release valve but routes it through the board state of the player you are attacking. The trigger is a may, and it only finds purchase when an opponent has a tapped creature worth waking up, which means the golem actively wants their attackers and mana dorks committed elsewhere before it can swing. The result is a creature that is reliably online against a deck tapping out to race you, and an inert 5/3 statue against control that holds up untapped blockers and never gives the trigger anything to grab. That conditionality, more than the rate, is what dates the design: a powerful body whose function is held hostage by an opponent's choices, from an era comfortable letting a creature do nothing if the table did not cooperate.
