Silver-Inlaid Dagger

A one-mana equip with a two-mana attach cost is already cheap, but the conditional rider is the design's whole purpose. The base +2/+0 makes it a generically playable weapon on anything, while the extra +1/+0 on a Human carrier turns a fine sword into a tribal payoff: the deck most likely to run it is also the deck that triggers the bonus on nearly every body it puts down. You do not assemble anything special, only attack with the creature type you were already attacking with, and the card rewards a curve-out rather than a build-around. The aggressive math is real but exposed: equipment commits resources to a single carrier, and on a board of fragile one- and two-drops a removal spell strands both the attach cost and the tempo behind it. Because the bonus lives entirely on power, it adds reach and never resilience: a defensive deck gains nothing from it, and the carrier is no harder to kill for wearing it. That narrowness is the point. The card has exactly one job, which is to convert a wide Human board into lethal a turn or two faster, and the design refuses to do anything else.
