Colossus of Sardia

An artifact from the era when nine mana was meant to feel like nine mana. The design is a study in friction: a 9/9 trampler is the kind of body that should end games, but the printing priced it with a tax almost nobody could pay. The doesn't-untap clause is not a drawback bolted onto a finished body; it does the whole job of holding the card in check, turning a colossal threat into something that attacks once and then sits tapped, unable to block or attack again, until its controller can scrape together another nine mana to wake it. The cruelest part of the design is where that reset is gated. The untap ability is restricted to your upkeep, which means it resolves before you have drawn or laid a land for the turn; you must already have nine mana on the battlefield at the start of your turn to swing again that turn. It cannot be powered out, attacked with, and quietly reset between blocks, and the upkeep window forecloses the kind of mid-combat trickery a colossal trample threat might otherwise enable. The Colossus was less a finisher than a monument: something you built toward, attacked with once, and then left defenseless while you found the mana to do it again. The design language it speaks (vanilla-ish fatties balanced by hard untap penalties) was largely set aside once large creatures were balanced through cost-to-effect ratios instead. It is a marker of how the game once reckoned with the number nine.
