Renegade Firebrand

Strip the Chandra away and this is a fragile 3/2: no evasion, no resilience, easily outclassed by anything sharing its mana range. Keep a Chandra alive, though, and it becomes a 4/2 with first strike, a creature that wins ground combat against most things its size and trades up into bigger threats. The mechanism is what makes it worth studying. The upgrade isn't a one-time enters-the-battlefield trigger or a tapped activation but a static condition checked continuously, so the body flips between two completely different combat roles depending on what else you control. That makes it a payoff wearing the costume of a beater, drawn for a focused planeswalker shell rather than a generically efficient red creature. The lineage is a familiar one for the color: cheap aggressive bodies with a conditional bump that only fires inside their intended archetype, a way to push a theme without printing a card that stands on its own. First strike is the natural reward here, the keyword red leans on to let an undersized creature win combat math it should lose, and it only arrives once you've paid the real cost: committing a Chandra to the board and protecting her long enough for the bonus to matter.
