Goldwardens' Gambit
Affinity has almost always been an artifact-count mechanic, so pinning it to Equipment specifically is the wrinkle here: the discount scales with the same permanents the payoff wants to distribute. The spell reads as expensive at eight, but a board with a handful of Equipment already deployed collapses that cost quickly, and every one of those Equipment then has somewhere to go. That is the real design trick. Equipment decks perpetually run into the same bottleneck, the equip tax and the shortage of bodies to carry the gear, and this answers both at once: five hasty attackers appear and the attach clause moves suits onto them for free, no equip cost paid. The tokens are Rebels, a creature type white has historically owned, showing up in red here as raw attacking mass rather than a tutor chain. The whole package is a single-turn alpha strike enabler, converting a wide Equipment shell that had been chipping in with one or two carriers into a lethal swing where every sword and axe finds a hand. The friction is that it does nothing empty-handed: cast it with no Equipment and you have paid full price for five 2/2s with haste, which is a poor rate. It wants a built board first, then rewards you for having assembled one.
