Protection has always been a color-and-quality shield: from red, from creatures, from artifacts. This one shields by parity, splitting the entire spread of mana values into two halves and letting you claim one of them on entry. The choice is where the design lives. Odd protects against Lightning Bolt, Path to Exile, and most one-drops but leaves you open to the two- and four-drops; even covers the common two-mana removal but not the one-mana burn or the three-mana sweeper you name off a spell. Because protection carries its full suite (can't be blocked by, damaged by, enchanted or equipped by, or targeted by anything of the chosen quality), the parity split turns a 3/3 body into a scalpel against a known removal package, at the cost of guessing wrong against the half you didn't pick. It rewards reading the opponent's curve before the creature resolves, and it punishes a misread by leaving a whole parity of answers live. What makes it sharp is that the two options are genuinely symmetric in coverage but never in matchup value: against a deck built on odd-cost interaction, choosing odd is close to hexproof, and against that same deck an even call is nearly dead weight. Protection had been printed a hundred ways before this; slicing the number line down the middle was a genuinely new axis for it.
