Chandra, Torch of Defiance

Four loyalty, four mana, and four directions to point it: this was the planeswalker that recalibrated how much a single red four-drop could do without tipping over. The first plus is the design statement, a forked choice that hands the player both halves of what red wants (card advantage and reach) and lets the board state decide which one matters. The second plus turns her into a mana source on legs, paying for spells across future turns. The minus-three is removal priced like a burn spell stapled to a body that sticks around to keep firing. The ultimate is a recurring damage engine of the kind red planeswalkers rarely got to keep. The genius is that none of these modes is a downgrade: there is no filler tick, no loyalty ability you activate only because the others are off the table. That density is what made her a default inclusion. Red had spent years being told its planeswalkers should be fragile, narrow, or both, the color's flagship walker more often a niche build-around than a four-of. This one was none of those things, and it largely set the modern template for "a planeswalker where every ability earns its slot." The lineage of tightly tuned red walkers that followed runs in no small part from how little slack this design left on any single line.
