Sai of the Shinobi

Most Equipment charges a tax every time you want to move it: the equip cost is the friction that keeps a suited-up creature from simply respawning its bonus after a board wipe. This one waives that tax under one condition, letting the +1/+1 hop onto each new creature as it enters, free of the equip cost, so long as the flow of bodies keeps coming. That reframes what the card is for. It is not a piece of gear you invest in and defend; it is a token buff that follows the parade, sticking to whatever entered most recently and asking nothing for the transfer. In a deck built to flood the board (recurring tokens, blink loops, cheap reanimation) the attach trigger fires turn after turn, and the modest stat bump compounds because it is always landing where the tempo is. The equip cost still exists for the cases the trigger cannot cover: reattaching after a sweeper, or moving the buff onto a creature already in play rather than a fresh arrival. The design is a quiet inversion of the usual Equipment math, trading up-front equip taxes for a cheap cast and free attaches, and betting that a wide, churning board will exploit those free attaches often enough to come out ahead.
