Myr Enforcer

The printed cost of seven is a deliberate fiction: nobody ever pays it. Affinity for artifacts turns this into a creature whose real cost is the board state in front of it, and in a deck stuffed with cheap artifacts (a fistful of Ornithopters, a Frogmite already down, an artifact land in every slot), a 4/4 body that lands for one mana or zero is the payoff that justified the whole archetype. What makes the design hold together is that the affinity discount is uncapped while the body stays bare: no evasion, no combat tricks, just a clean 4/4 and its discount. That plainness is the point. The card is a payoff, not an engine, so the work happens elsewhere (in the artifact count you build up), and Myr Enforcer is what cashes it in. It sits one rung above Frogmite in the same skeleton: where Frogmite is the early beater that comes down on turn two for a single mana, the Enforcer is the heavier closer that rides the same artifact density to a bigger frame. The whole affinity mechanic was an experiment in whether you could divorce a spell's mana value from its mana cost, and few cards expose that gap more starkly than a 4/4 that reads as a seven-drop and casts as a one-drop. The answer the format eventually gave: yes, and too well, which is why affinity's enablers, not its payoffs, took the bannings.
