Payoff
Deck
- Legend domains only need Order — LeBlanc is Order and the Lab is colorless, so any Order legend runs it.
- You must CONTROL the Lab. 190.6.d: "'You' in a battlefield's abilities refers to the battlefield's Controller, as does the implied 'you' in instructions that don't specify a player like 'draw 1.' If the battlefield has no Controller, 'you' refers to no one, and all such instructions are ignored." 190.1 makes a battlefield you brought start uncontrolled, so walking a body there is part of the cost.
Prerequisites
- THE SECOND BODY AT THE LAB IS AN INGREDIENT, AND THE CLEANUP IS ONE STEP LATER THAN IT LOOKS. Kill LeBlanc and 319.6 makes a Cleanup Outstanding — but her Deathknell is already a Pending Item on the Chain (808.1.d), so the turn is Neutral Closed (310.2) and 323.6's 'if the turn is in an Open State' is FALSE: control is not stripped there. The Deathknell resolves (340.1), the Chain empties, 319.1 makes a second Cleanup, and THAT one runs 323.6 and takes the Lab off you — still before 315.2.b.2 Holds. So with LeBlanc as your only body there you draw the three cards and lose the point; with a second body you keep both.
- THE TIMING IS PRINTED ON BOTH CARDS AND CONFIRMED BY THE PHASE RULES. 315.2.a.1 ('At the start of Beginning Phase game effects take place') is the Beginning Step; 315.2.b.2 ('The Turn Player Holds all Battlefields they Control') is the Scoring Step after it; both are inside the Beginning Phase (315.2). So 'If it's your Beginning Phase, draw 2 instead' is live, and the Lab's own reminder text says '(This happens before scoring.)'.
- ARITHMETIC WITH THE QUANTITIES DECLARED. 1 card from the Lab + 2 from the Deathknell = 3 CARDS FOR 0 ENERGY AND 0 POWER, at the start of each of three Beginning Phases. LeBlanc costs E3 + 1 Power on an earlier turn, so the line is 3 cards for 3 Energy + 1 Power spread over two turns. After the three copies are spent the Lab keeps paying 1 card a turn for any spare body — including a token, since killing a token is a kill (186.1 only says it ceases to exist afterwards).
- BURN OUT IS THE CEILING AND IT ARRIVES EARLY. The three cards land in the Beginning Phase, BEFORE the Draw Phase (315.4.b, 'The Turn Player draws 1'). 431.1.a then draws what is left of a thin deck, 431.2.c gives an opponent a point and 194.1.d records it. Do not run this line on an empty deck.
- A BATTLEFIELD IS RANDOM 1 OF 3 IN DUEL (485.5) AND SKIRMISH (487.5), CHOSEN IN MATCH (486.5), and 103.4.c plus Tournament Rules 402.1 forbid carrying two of a battlefield with the same name, so three copies are not a way to make it certain. 485.4.a: 'Each player provides three (3) Battlefields ... Only 1 will be used, chosen during setup.'
- NOT A DUPLICATE OF karthus-leblanc-fragmented-temporary-draw. Same LeBlanc, different killer: that entry marks her with [Temporary] from Shadow's Call and doubles the Deathknell with two Karthus (R1 = A); this one needs no second card at all and repeats every turn the Lab is yours. They share no card but LeBlanc.
Steps
- Bring Dusk Rose Lab and take control of it — 190.1 means it starts uncontrolled and its text is off until you do.
- Play LeBlanc, Fragmented (3 Energy + 1 Power) and get her to the Lab, with at least one other unit of yours standing there.
- Your next Beginning Phase, Beginning Step (315.2.a.1): the Lab's trigger goes on the Chain. Kill LeBlanc. Draw 1.
- Her Deathknell triggers (808.1.d). It is your Beginning Phase, so it draws 2.
- The second body keeps the Lab occupied, so 323.6 never strips your control and 315.2.b.2 Holds it in the Scoring Step for the point.
- Repeat with the second and third LeBlanc; afterwards the Lab still trades any spare body for 1 card a turn.
Per iteration
3 cards at the start of your Beginning Phase for 0 Energy and 0 Power, on each of three turns; 1 card a turn afterwards for any spare body
How it ends
engine only — three big turns, one per LeBlanc, then a permanent 1 card a turn; the ceiling is Burn Out (431.1.a), not the cards

HAND-WALKED 2026-09-06 (docs/phase0/walks/2026-09-06-draw-lens-candidates.md), issue #59 candidate 2. UNL-209 Dusk Rose Lab appeared in no entry before this. Card text verbatim from data/corpus_flat.txt; 190.1, 190.6.d, 310.2, 315.2.a.1, 315.2.b.2, 315.4.b, 319.1, 319.6, 323.6, 340.1, 431.1.a, 431.2.c, 194.1.d, 485.4.a/485.5/486.5/487.5 and 103.4.c opened in the Core Rules. Ban check: neither card carries a [BANNED marker. THE WALK'S ADDITION over the hunt: the hunt said losing your last body at the Lab strips control 'before 315.2.b.2', which is true, but traced through 319/323 it happens at the SECOND Cleanup, not the first — the Deathknell holds the turn in a Closed State (310.2) and 323.6 is conditioned on an Open one. Trap check: no attack designation ([Assault] is a Might modifier, not a trigger); no [Repeat]; no [Temporary]; no Gold; no recall, so 808.1.d.1 never engages and the Deathknell is safe; the battlefield caveat is declared. Depends on no unruled reading.
