Knowledge Exploitation

Praetor's Grasp and Bribery and the whole tradition of reaching into an opponent's library start from the same impulse: their cards are better than yours, so take theirs. This one narrows the target to instants and sorceries and adds the twist that you cast the stolen spell for free the moment you find it. The cost is where the design gets honest. Seven mana for a one-shot theft is a steep rate, and the card knows it: prowl drops the price to if a Rogue connected for combat damage earlier that turn. That conditional turns an overpriced curiosity into a payoff, but it sets a strict sequence first. Because prowl reads the combat damage off the current turn, the play is a single arc: swing with an evasive Rogue, then cast this in the same post-combat main phase. The timing detail that shapes what you can actually take is subtler than it looks. This is a sorcery resolving into an essentially empty stack, and you cast the found spell directly from the library during that resolution: a pure counterspell has nothing to target, so it never gets cast and simply stays buried when the library shuffles. The real prizes are proactive cards: an opponent's removal aimed back at their own board, a tempo swing, a burn spell, a tutor. The free recast is the flashy part, but it is the four-mana version, the one you earned in combat, that justifies the steal; left at seven, it is a slow and clumsy theft.
