Scavenged Brawler

Most keyword-counter designs pick one keyword and grant it as a counter; this bundles all four of its own into a single graveyard-fired package, then staples four +1/+1 counters on top of the choice. The six-mana Construct body is a fine-if-unremarkable evasive lifelink beater, but the ability is where the card's logic lives. Once it dies, exiling it from the graveyard for five reads like a second casting: you pay again, and instead of getting a 4/4 back you turn any creature on the board into a flying, vigilant, trampling, lifelinking threat four counters larger. Keyword counters do the same structural work granting them does, with one difference that matters against certain answers: a counter is not an aura or an Equipment, so spot removal that strips buffs by killing the enchantment or unattaching the gear leaves the counter-loaded creature untouched. It is still a creature, so a wrath, a bounce, or a blink erases everything, the way it erases any pumped board. The sorcery-speed restriction is the tax that keeps this from being a combat-trick blowout: you commit to the pump on your own turn, telegraphing it, rather than ambushing a block. And because the activation exiles the card, it is a one-shot resource, not a recurring engine, which is what separates it from the recursive value pieces its lifelinking, self-buffing profile superficially resembles. The Construct dies; its keywords get laundered onto something built to survive.
