Tivadar of Thorn

A hate card with a name and a grudge. The original Tivadar's Crusade was a one-shot effect aimed squarely at Goblins, and this Knight carries that vendetta onto a body: enter the battlefield, kill a Goblin, then stand on the table swinging through any red attacker untouched thanks to protection from red. Every line of the card points the same direction. First strike plus protection from red means Tivadar wins every combat a red creature could pick, blocking or attacking, without taking a scratch; the enters trigger spends itself dismantling whatever Goblin board the opponent has built; protection neutralizes the red burn that would otherwise answer a three-mana creature cleanly. The trouble with building a card this narrow is that it folds the moment the opponent is not playing red Goblins, and that is the honest cost here: against any deck without a Goblin the destroy trigger fizzles and the protection clause never matters, leaving a 2/2 first striker whose every advantage is pointed at an opponent who isn't there. It is a designed answer wearing a designer's wink, a callback to an early-era sideboard staple rebuilt as a legend so the flavor and the function could finally sit on the same card.
