Redeem the Lost

Protection at instant speed has always been a deceptively complete answer: it dodges targeted removal, walks a blocker through combat, and shrugs off a single attacker, all from one card and one decision about which color to name. The wrinkle here is what the design bolts onto that effect: a clash, which turns a normally one-shot trick into something that might pay for itself. Win the clash (your library's top card has the greater mana value) and the trick comes back, so the protection cost you nothing but the mana. The trade built into that upside is honest. Clash is a coin flip skewed by the shape of both libraries, not a guaranteed refund, and the card asks nothing of you to play it whether you win or lose, so the buyback is a bonus rather than a tax. It is the recurring tension in clash design from this era: the headline rate is fair on its own, and the clash is a free roll stapled on top that rewards a deck willing to weight its curve high enough to win the reveal more often than not. The protection effect does the work regardless; the clash just decides whether you keep doing it.
