Gate Smasher

The toughness gate is the whole point. Most cheap aggressive Equipment hand out a power boost to anything with a creature type and a pulse; this one refuses to attach unless the bearer already sits at four toughness or better, which writes its own deck list. A +3/+0 trample buff is loud on a fragile attacker, but the restriction quietly funnels it toward the creatures that least need help surviving combat: walls, ramp bodies, defensive midrange beaters that carry a healthy bottom number and just want a way to push damage through a clogged board. That inversion is the design idea. Trample matters precisely because the natural carriers are big, sticky things that opponents are happy to chump-block all day; bolting reach onto a 0/4 or a 4/5 turns a roadblock into a clock without asking it to take risks it was never built to take. The equip cost is steep enough that this is not a tempo play; it is how a defensive shell cashes in its accumulated toughness for a finish. What separates it from the usual "your big dumb creature now closes the game" tools is that the toughness clause works as an honest tax: you do not get the upside unless you have already committed to fielding the kind of creature that earns it.
