Dusk Legion Duelist

White's cheapest card advantage usually costs something the color would rather keep: life, a wasted attack step, or a creature that would prefer to be swinging. This one asks for a mechanical trigger instead, drawing whenever a +1/+1 counter lands and capping the reward at once per turn. That clause is the whole balancing act: the reward tracks how many separate turns you can feed it a counter, not the size of any single pump. Dumping five counters onto it in one combat step draws exactly one card, the same as a single counter would, so the design steers you toward a steady drip rather than one explosive turn. The engine wants sources that place a fresh counter every turn: a proliferate outlet you can fire each cycle, a repeatable pump ability, any effect that reliably touches it once per turn. Anthem-style static buffs do not qualify, since they raise the number on the card without placing a counter; the trigger only reads genuine counter sources. The vigilance does real work too, letting the body pressure the board and still hold back to block, which keeps it alive to draw again on both halves of the clock. Structurally it belongs to the lineage of cards that reward reinvesting in a single creature, the Ordeal-style idea of a body that pays you for pumping it, rebuilt as a repeatable draw engine instead of a one-shot burst.
