Karplusan Hound

A 3/3 body hung on a single condition, and the condition reads off a type line rather than a name: the recurring damage fires only while you control a Chandra planeswalker, any Chandra. That gate is binary, a yes-or-no check that pays a flat 2 damage whether you have one Chandra or three, and it declares what this Dog is: not a splashable creature but a threat that goes inert the moment the planeswalker leaves the board. What makes the trigger sing is its timing. It fires on the declaration of an attack, not on combat damage, so the ping lands before blocks are chosen and resolves whether or not the creature survives the swing. Declare the attack, sweep a two-toughness blocker off the board, then send the body in unopposed; or aim the 2 damage at a rival walker's loyalty or the last points of a life total. Firing pre-blocks turns the attack step itself into a repeatable removal spell. The design is a quiet inversion of how red usually links creatures to planeswalkers. The common relationship is loyalty support: bodies that guard or accelerate the walker. Here the walker is the enabler and the creature is the finisher, the planeswalker doing the work a tribal lord would, keying a payoff off a shared type. The honest read is a narrow build-around: dead weight on its own, genuinely dangerous inside the one deck it was drawn to serve.
