Ajani, Nacatl Pariah // Ajani, Nacatl Avenger
Most transforming planeswalkers flip on a clock you set: a mana threshold, a life total, a payoff you build toward. This one flips on a Cat's death, and the trigger is the whole design conceit. The front half is a small creature that comes down with a token attached, and the flip condition asks you to spend Cats to earn the walker: any death among the other Cats you control, including the token he arrives with, opens the exile-and-return window. That reframes the enters trigger from value to fuel. The clumsiest board of one-drops becomes a resource the planeswalker is waiting to convert.
The back half is where the design bends toward Boros. The zero ability makes another token, but if you control a red permanent other than Ajani it turns into a burn spell scaling off your creature count, quietly rewarding the aggressive Cat board the front half was assembling. The plus grows the whole team, and the ultimate is a Cataclysm-style board reset that lets each opponent keep an artifact, a creature, an enchantment, and a planeswalker and buries the rest. What holds the package together is the seam: the creature and the walker want the same thing, a wide Cat board, and the flip mechanic is engineered so that going wide and then trading in a body is not a cost but the intended path to the second card. It is a rare instance of a two-sided planeswalker whose halves are not two modes but one continuous strategy.
