Sabertooth Outrider

A 4/2 trample body for four mana lives or dies in combat math: enough power to demand a block, too little toughness to survive most of what blocks it. The Formidable clause is the reward for going wide, granting first strike on attack once your board's total power crosses eight. That threshold is the design's whole proposition. First strike on a 4/2 trampler is genuinely punishing, turning a creature that trades down into one that kills its blocker and shovels the excess over the top, but it only switches on when you have already built a battlefield big enough that the bonus is gravy. This is the recurring tension in threshold-style abilities: the payoff arrives precisely when you least need a single creature to overperform, and stays dark on the turns you would most want the help. Formidable checks board state rather than a counter or a graveyard, so it rewards a curve that floods early and asks nothing of you beyond playing creatures, which makes it a clean fit for low-to-the-ground aggressive decks that want every body pulling weight in the red zone.
