Bespoke Battlegarb

Most Equipment asks you to pay twice: once to cast it, again to strap it on. The Celebration clause is the reprieve, folding that second payment into a combat-step trigger whenever your board has churned enough that turn (two nonland permanents, a threshold a go-wide or token deck clears without trying). What makes this design worth studying is where it puts the free attach: at the beginning of combat, before attackers are declared, so the +2/+0 lands on a creature that is about to swing rather than one sitting back. That timing is the whole point. It turns a two-mana rock of an Equipment into a repeatable, no-mana pump that redirects to your best attacker each turn, moving with the board as blockers and threats shift. The equip cost is still there as a fallback for the turns you fail to trigger Celebration, but the card is built to be free far more often than it is paid for. It is a clean expression of the "reward for developing your board" ethos: the buff scales with how busy your turn already was, and the effect is at its worthless on an empty battlefield and at its best on the exact turn you wanted a haymaker anyway.
