Ante is the angle here, and few cards expressed it more pointedly. This is a rules-bending mugging dressed as a creature: tap and sacrifice a 3/3 body to force an opponent into a Sophie's choice between ten life and surrendering a random card from their hand, permanently. The exchange clause is where the design lives. Most ante cards rotated cards in and out of the ante pile during a game; this one rewrites ownership outside the ante system entirely, which is why the reminder text up top exists at all. It carries the explicit "remove from your deck if you're not playing for ante" tag that the DCI used to quarantine the ante subset, and it sits on the permanent banned list in every sanctioned format alongside the rest of that cycle (Bronze Tablet, Contract from Below, Jeweled Bird, and the others). What sets it apart from its peers is the price the opponent pays to refuse: ten life is a real number, high enough to feel like a tax but low enough that the opponent will sometimes pay, which gives the card a genuine decision point its siblings lack. Now it survives mostly as evidence of what an early designer thought the cost of permanent card theft ought to be: a 3/3 body and a tap to sacrifice it, against an opponent's wager of ten life.
