The Destined Warrior

Full party is the mechanic that never quite justified building around it, because the party system asks you to field one member each of four specific classes, and spreading your creatures across those roles competes directly with just running your four best creatures. This resolves that tension by paying you twice. The cost reduction discounts exactly the class spells you were already leaning on to fill out the party, so the deck curves out faster than its scattered typeline suggests. The combat trigger is where the constraint bites: it is a binary check, not a gradient. Fall short and every combat still hands your board a modest +1/+0. Assemble all four classes and the same trigger flips to a team-wide +3/+0 every turn at no additional mana. That all-or-nothing threshold is the whole design axis: the floor is generous enough that the trigger is never dead, and the jump to the ceiling is steep enough that you feel the reward for committing rather than approximating. The keyword suite stays on the body alone. First strike, vigilance, and menace make its attacks awkward to block and let it swing without abandoning defense, so it stays a repeatable threat while the anthem does the boardwide work. The result is a payoff shaped to punish you for treating party as a bonus instead of a build, which is precisely the shape the mechanic needed to anchor a deck.
