Kaito, Cunning Infiltrator

The self-loyalty engine is the whole design. Most three-mana planeswalkers protect themselves by generating blockers or answering threats; this one instead ties its survival to the offense it's built to enable, gaining a loyalty counter every time any of your creatures connects with a player. That inverts the usual defensive posture: rather than parking on high loyalty and grinding, it wants your board attacking every turn, converting combat damage into fuel that outpaces the loyalty you spend. The +1 does double duty, threading a creature past blockers while smoothing your draws with a loot, so the same activation that pushes damage also refills the hand that lost tempo making the attack. The −2 rebuilds a body when the board thins, a self-contained 2/1 Ninja to keep the trigger loop alive without leaning on anything else you've drawn. And the emblem is the payoff a walker like this rarely reaches unaided: by the time you've assembled enough loyalty to fire the −9, the combat engine has usually already won, but a spell-triggered token factory turns a stalled game into an inevitability. What makes the piece cohere is the feedback loop: every element feeds the loyalty ramp that unlocks the next, so the correct posture is aggression rather than shelter. A planeswalker whose defense is that you keep swinging.
