The reduced-equip clause is the entire pitch. Equipment usually carries a fixed retrofit tax: you pay the same cost to strap it on whether the creature was built for it or not, and that flat cost is what keeps a repeatable +2/+2 aura from being oppressive. Here the tax is conditional. A Knight equips for one mana; anything else pays three. That split turns a mediocre generic Equipment into an aggressively priced one that only works if your board is on-theme, which is exactly the deckbuilding contract a tribal aggro deck wants: it prices out the goodstuff-pile decks that would otherwise slot a cheap stat-stick, and rewards the player who committed to a creature type. The two-color casting cost narrows it further, tying the card to a specific aggressive color pair rather than letting any Knight deck run it. As a body-pumping tool it is plain: no evasion, no protection, no ability granted, just a size increase that pushes damage through and lets a small early creature keep trading up. That plainness is the point. It was built for a shell that needed a cheap way to make its one- and two-drops relevant into the mid-game, and it does that job for the decks it was designed for and almost nothing for anyone else.
