Kaima, the Fractured Calm
Auras that target opponents' creatures have always sat in an awkward spot: putting a Pacifism or a Faith's Fetters on a rival's threat spends a card to solve one problem, and the moment that creature dies your Aura is a spent match. This legendary rewrites the exchange by attaching a payoff to the very act of enchanting other people's board. Goad turns those enchantments into a redirection engine, forcing each enchanted creature to swing at someone other than you, and every creature bent that direction pumps the body that did the bending. The end-step timing is the wrinkle that makes it work: goad resolves after your own combat is over, so you set up the political violence for the turn cycle ahead rather than committing anything of your own, and the counters accumulate on a permanent basis rather than resetting. What lands elsewhere on the board (a Claustrophobia here, a Frogify there, even beneficial Auras that count all the same) becomes both a diplomatic lever and a growth clock. The design leans on a truth most Aura decks ignore: an enchantment on an enemy creature is a resource you can keep taxing, not a one-time answer. Building around it means treating opponents' bodies as your targets and their combat steps as your engine, with a 3/3 that stops being a 3/3 the first time it forces three creatures to attack anyone but you.
