Defender of Law

The rare hatebear whose two pieces of text actually reinforce each other. Protection from red blanks burn, blocks red attackers cleanly, and means the creature cannot be targeted by red removal at all; flash means it gets to do all of that on the opponent's turn, arriving as a surprise blocker that survives the combat math an aggressive red deck just committed to. The design discipline here is the body: a 2/1 is small enough that protection from red is the only reason it earns a card, which keeps the answer narrow and the rate honest. Most protection creatures of this period were vanilla bodies stapled to a color hate-clause and asked to attack into the matchup. Adding flash changes the axis entirely, turning a proactive beater into a reactive trap that punishes the red player for attacking and for assuming the board was safe at end of turn. The red mage who swings into open white mana finds a blocker that eats the attacker, ignores the burn spell pointed at it, and walks away. Urza's Legacy used a handful of white flash creatures with protection to push the idea of instant-speed defense, and this is the cleanest version of it: a card that is dead against most of the field and devastating against exactly one color, with the flash riding shotgun to make the narrow case as punishing as possible.
