Chandra, Flamecaller

Six mana buys three planeswalker modes that almost never share a turn, and that spread is the whole point. The +1 is reach disguised as defense: six hasty power that exiles itself at the next end step, which means it asks to be swung the moment it arrives rather than parked behind a wall to protect loyalty. The 0 is the rare card-advantage button that costs nothing in loyalty, a wheel-for-one stapled to a body that can keep firing it turn after turn. And the minus is a scaling sweeper that hits each creature, your own included, so it is a symmetrical wrath that pays you only when your board is already empty. That symmetry is exactly why the token mode and the sweeper occupy different turns by construction: the Elementals are gone before your next upkeep, so the genuine tension is never between going wide and wiping, but between which single mode each turn can spare. That choice is what separates this Chandra from her cheaper, more linear incarnations. Most red planeswalkers commit to one axis (burn the face, burn the board, generate pressure); this one carries pressure, refuel, and removal in the same card and trusts the pilot to read which the turn needs. She enters at four loyalty and can immediately spend down to clear the board, which makes the minus removal that walks in with its own clock attached. This is the toolbox interpretation of mono-red's planeswalker design, built for the deck that wants every card to answer the board rather than do the one thing it was drawn to do.
