Chandra, Legacy of Fire

Two of the three abilities scale off a single number: how many planeswalkers you control. The passive turns each one into a point of end-step reach at every opponent, so a wide loyalty board becomes recurring damage without a single attack. The +1 funds mana the same way, letting a crowded table of walkers bankroll an oversized turn. This is the payoff at the top of a superfriends pile, the card that converts a board of planeswalkers into damage and ramp at once. The 0 is the strange one, and it does not care about planeswalkers at all: you pull a loyalty counter off any number of your permanents (planeswalkers, mostly, but anything carrying loyalty qualifies) and impulse-draw an equal number of cards. That clause treats loyalty as fungible currency rather than a per-card health bar. Spending loyalty you were never going to use converts stalled counters into a burst of cards; the trade is real, since draining a walker's loyalty pushes it away from its own ultimate, not toward it. None of this does much in isolation the way a two-drop planeswalker does. She is a capstone, engineered for the archetype where planeswalkers are the deck rather than the support, and the reward curve bends sharply upward the more of them you have already resolved.
