The Circle of Loyalty

Affinity almost never lands on white. The mechanic was built for the artifact-density decks that count Ornithopters and Springleaf Drums, so pinning the discount to a tribal counter (Knights, specifically) is the design wrinkle: the cast cost bends downward exactly as the board it rewards grows wider, so the deck already committed to going wide pays less for the payoff that makes going wide better. It is an anthem that also builds its own board (a token on every legendary spell, plus a repeatable activation), and a legendary artifact that quietly encourages you to run more legends to feed the token trigger, folding two separate incentives (go wide on Knights, go tall on legendaries) into one static pump. The deeper move is where the +1/+1 lives. A creature lord dies to a removal spell and leaves the board deflated behind it; parking the anthem on a noncreature artifact takes the pump off the axis creature removal can reach, and it survives the wraths that scour the tokens beneath it, keeping the board buff intact while a fresh activation refills the line. It still answers to artifact removal, and losing it drops the token engine along with the anthem, but a Terminate or a Bolt to your best Knight no longer collapses the whole build. That balance between an early affinity-discounted arrival and a mana value that stays honest, propped up by the anthem and two token faucets, is what the tribal counter is buying.
