Bloodfray Giant

Unleash put a knob on every creature that carried it, and this Giant shows the mechanic at its plainest: pay nothing extra and you have a 4/3 trampler that can still hold the ground, or accept the counter and swing for 5 with the understanding that it can't block while the counter remains. The keyword's whole pitch was to let one card serve two roles, an aggressive build and a slower one drawing different value from the same shell, with the irreversible commitment (a creature with the counter can't go back to blocking) acting as the price of the bigger body. Trample is what makes the unleashed mode worth the trade: a 5/4 that can't block wants to be attacking past chump-blockers anyway, so the keyword's downside and the evergreen ability point the same direction. The decision is front-loaded and permanent, which is the design discipline here: you choose your role the moment it resolves and live with it, rather than re-evaluating each turn. As the red entry in the Unleash cycle this is the colorpie-correct one, a vanilla-adjacent beater whose only text is the choice it asks you to make on the way in.
