Two creatures, frozen for a turn cycle, the moment this Wizard hits the table: that is the entire pitch, and everything about the card bends toward making it count. The effect threads a narrow gap. It is broader than a tapper (one body instead of two) and narrower than removal, which answers a creature for good. Detain is a loan, not a gift: until your next turn, the two targets can neither attack nor block, which clears the path for an immediate swing into a board missing two of its defenders. The window closes the instant your next turn begins, so by your following combat those creatures are blockers again; the lock buys exactly one of your attack steps, no more. The clause that shuts off activated abilities is the underrated half: while the detain holds, mana sinks and pump effects on those two creatures go dark, so a frozen blocker cannot pump or sacrifice its way into relevance during the window. The 2/2 frame is incidental; the value is all in the enters trigger, and once that has fired the card is a vanilla body any opponent can trade away. That front-loading is the bargain the keyword strikes. Where white usually pays its tempo for permanent, attrition-proof answers, this hands you a swingy, temporary advantage with a deadline attached: convert the opening into a real lead before the lock expires, or you have spent four mana to inconvenience an attacker for a single combat.
