The activated ability is the whole reason this turns up in decks that otherwise have no answer to a protected permanent. For one generic mana, at instant speed, it strips hexproof and indestructible off everything your opponents control at once: a stapled-on solution to two of the most obstructive defensive keywords in the game, available to any deck that runs artifacts, which is to say nearly all of them. Colorless removal-enablement of this scope is rare. A red aggro deck can suddenly burn down an indestructible blocker; a deck holding targeted spot removal can finally point it at a hexproof creature that was untouchable a moment earlier; neither had to warp a mana base to do it. The +1/+1, trample, and lifelink are almost a courtesy: a one-mana Equipment that turns a token into a resilient, life-swinging attacker would earn a slot on those stats alone. What holds the package together is that the equip cost and the live combat-relevant ability never compete. The card is never a dead draw, because when you need the stats you equip, and when you need to break through protection you spend the one mana and leave the Equipment on the battlefield for later. It answers a problem that keyword accumulation created: as hexproof and indestructible spread across sets, decks leaning on removal to unstick a game found their answers routinely blanked, and this handed them a key in the cheapest, most color-agnostic slot available.
