Rakeclaw Gargantuan

A 5/3 wants to swing, and a 5/3 swinging into open blockers usually trades down or dies for free. The first-strike grant is built to patch exactly that, but the wording matters more than a self-buff would: it can target any sizable attacker, not just this body, so on a board of fatties it becomes a repeatable combat tax. Pay one mana and your biggest threat eats a blocker before it absorbs anything back. The threshold on what it can buff is the price of that reach. It locks the effect away from cheap, evasive creatures that would abuse a free first-strike enabler, and it ties the payoff to a board state you must already have built tall, where the grant is least needed and most expensive to assemble. As a multicolor beater, it rewards a deck that was stacking large creatures anyway and does nothing for a deck that wasn't, a self-referential upside that falls flat outside its lane. The brittle toughness is the honest read here: this hits hard and dies easily, holding an ability it would rather aim at something sturdier than itself.
