Standard targeted discard shows you the whole hand: Thoughtseize and Duress reveal everything before you choose what to take. This enters-the-battlefield ability inverts that bargain. Instead of seeing the full hand and stripping the best card freely, you buy your view of it, one card per life paid, and you only get to exile from the slice your opponent reveals. Pay one and they show a single card of their choosing; pay enough to match their hand size and you finally see the whole thing the way ordinary discard hands it to you for free. But the opponent controls which cards surface, so a careful pilot keeps the card that matters tucked behind the ones they can afford to show. The life total is the currency, spent for incomplete information rather than an open hand. That makes it a stranger, greedier piece of disruption than the format staples it resembles: deeper visibility costs more, and the opponent still gets to bias what you learn unless you bleed for enough reveals to corner them.

Extort on the 1/3 body is what reconciles the math. Every time you cast a spell after this lands, you may pay a white or black mana to drain each opponent for one and gain that much back, so the resource the discard ability spent is one the keyword slowly recovers over a long game (and against multiple opponents, faster). It points at a grindy white-black attrition shell where life is a resource to recycle, not a clock you are racing down: the entry is the wager, and the body keeps paying it back one cast at a time.
