Cull the Weak is 355.10.e's own worked example, so it cannot be Deflected — and Loyal Poro makes the half you pay draw you a card

Payoff
Deck
- Both cards are mono-Order, so 103.1.b.3 admits any legend with Order in its pair: SFD-201/SFD-249 Chem-Baroness, UNL-199/UNL-235 Deceiver, SFD-197/SFD-247 Emperor of the Sands, VEN-147/VEN-193 Eye of Twilight, SFD-205/SFD-251 Grand Duelist, UNL-195/UNL-233 Green Father, OGN-253/OGN-302 Hand of Noxus, VEN-155/VEN-197 Heart of the Tempest, OGN-265/OGN-308 Herald of the Arcane, UNL-203/UNL-237 Keeper of the Hammer, OGS-021 Lady of Luminosity, VEN-153/VEN-196 Matriarch of War, OGS-023 Might of Demacia - Starter, UNL-187/UNL-229 Piltover Enforcer, OGN-261/OGN-306 Radiant Dawn, OGN-269/OGN-310 The Boss, SFD-187/SFD-243 Void Burrower.
Prerequisites
- WHAT YOU BUY AND WHAT YOU DO NOT. The opponent chooses their own casualty, so this is not removal you can aim — they will give up their worst body. What it IS: two Energy and a Power that no [Deflect] can tax, that no counter keyed on choosing can see, and that reaches a unit which is otherwise untouchable at their base. Against a board of one it is a clean answer; against a wide board it is a tax.
- AND YOUR HALF IS NOT A COST — IT IS THE OTHER HALF OF THE ENGINE. Loyal Poro's Deathknell turns the unit you were obliged to kill into a card, so the spell reads 'each player loses a unit, and you draw 1'. 808.1.a puts the Deathknell on the permanent and the Poro reaches the Trash normally here (nothing replaces its death), so 808.1.d.1's shield trap does not apply.
- 740.2.a IS THE PARAGRAPH, NOT THE REMINDER TEXT: 'A unit is alone when there are no other friendly units at the same location.' The project had been reading 'alone' off the pool's own reminder lines; it is defined in the glossary. The practical consequence is that the Poro must be standing WITH somebody — at your base or at a battlefield — and a Poro alone at a battlefield draws nothing.
- IT IS SYMMETRIC IN FORM AND ASYMMETRIC IN PRICE, which is the whole reason to run it: you have paid E3 for a body that replaces itself when it dies; they have paid full price for whatever they give up.
- THREE CASTINGS (103.2.b) AND THREE POROS, so the pairing is bounded at three even before the deck runs out of second bodies. Nothing here loops.
- 355.10.f IS THE SIBLING CLAUSE and worth keeping straight: an instruction a player 'must' complete also targets nothing, which is why OGN-287 Sigil of the Storm's forced rune recycle chooses nothing either. Both are in this domain.
Steps
- Play Loyal Poro (E3) and keep it standing with at least one other friendly unit — 740.2.a measures 'alone' at its location, so a lone Poro at a battlefield does not qualify.
- Cast Cull the Weak (E2 + 1 Order Power). It targets nothing (355.10.e), so no Deflect Value is added to its cost however protected their board is.
- On resolution each player chooses one of their own units and kills it. You choose the Poro; they choose whatever they can spare.
- The Poro's Deathknell resolves from the Trash: it did not die alone, so you draw 1.
- Repeat with the second and third copy. 103.2.b caps both halves at three.
Per iteration
one enemy unit dead anywhere on their board and one card drawn, for E2 + 1 Order Power and a body that replaced itself
How it ends
engine only — three castings (103.2.b), each costing the opponent a unit of their choice and costing you a card-neutral Poro; nothing here scores

REFUTE = a refutation pass, with its date and verdict · WOUNDED = the pass found a flaw and the entry was rewritten · BUDGETED = the pass checked the recycle-and-draw ledger · lens = the hunt that proposed it.
HAND-WALKED 2026-09-07, issue #180 — the first entry to use OGN-209 or UNL-156. Card text verbatim from data/corpus_flat.txt. Cull the Weak's wording is Riot's own worked example for 355.10.e, which is the strongest citation shape this project recognises. Trap check: the entry states plainly that the opponent picks their own casualty, so it is not sold as aimed removal; 740.2.a is cited for 'alone' in place of the reminder text the project had been reading it off, and the second body it implies is stated as a requirement on the Poro's zone rather than left in prose; 808.1.a and 808.1.d.1 are checked so the Deathknell is known to fire (nothing replaces this death); 355.10.f is named as the sibling clause so the two are not conflated.
