155 is what separates the Order removal ladder — Vengeance is cheaper and wider and can never take a battlefield, because the Conquer happens inside the Showdown

Deck

Both cards are mono-Order, so 103.1.b.1 is satisfied by any legend with Order as one of its two domains. Neither is Signature, so 103.2.d.2 imposes nothing.

Prerequisites

155 IS THE WHOLE LADDER: 'A spell can be played during an Open State outside of Showdowns on its controller's turn.' That is the default, and [Action] is the exception (806.1.b: 'permission to be played or activated during Showdowns, even when it is not the Controlling player's turn'). So `OGN-229 Vengeance` — E4 + 2 Power, 'Kill a unit', no location clause and no gate — is cheaper and strictly wider in WHAT it can kill, and it can never do this job, because it cannot be played once the Combat has opened.
THE CHAIN, IN ORDER. Move in (190.3.a.1 applies Contested), 323.9 stages the Combat, 323.13 opens it; inside the Showdown, kill the last defending unit; 465.1 makes the damage tasks Outstanding only 'If both Attacking and Defending units remain at this battlefield', so with the defence empty no damage is assigned at all; 466.3.a: 'A Player has won a combat if they received either the attacker or defender designation and are the only Player that has units remaining at this battlefield during this step'; 466.5 establishes Control and 466.5.d — 'Establishing Control results in a Conquer if that player has not yet scored this Battlefield this turn.'
A BLOODLESS CONQUER GENERATES ZERO EXCESS DAMAGE. 465.1's tasks never become Outstanding, so nothing is assigned and R28's 'attacking Might that never got assigned' has nothing to measure — the removal-conquer family and the six excess-damage cards are mutually exclusive in principle, not merely by domain.
AND IT IS CAPPED AT TWO A TURN WHATEVER YOU SPEND. 469.1 defines a Conquer at a battlefield 'not yet Scored this turn', 470 caps Scoring once per battlefield per turn and 485.4 puts two battlefields on a Duel table. Three Blasts of Power do not buy three Conquers.
THE ATTACKER HAS TO SURVIVE TO THE STEP, WHICH IS WHY A BODY IS IN uses[] AND NOT IN A NOTABLE. 466.3.a asks who 'has units remaining'; if the defender's removal answers yours first there is no winner and 466.3.d is No Result. Vanguard Sergeant is chosen for being the cheapest mono-Order body with no text to lose — the line wants a garrison, not a payoff.
TWO NAMED MEMBERS OF THE SAME FAMILY ARE BANNED IN BOTH FORMATS (`OGN-168 Fight or Flight` and `SFD-122 Called Shot`, both marked `[BANNED constructed:banned, 2v2:banned]` in `data/corpus_flat.txt`), which is worth knowing before a list is built on the shape.
AND THE LADDER'S OTHER RUNGS ARE PRICED THE SAME WAY: `SFD-158 Sandshifter` is a body and gated at Might 3; `VEN-131 Decree of Unity` is E2 + 1 Power and gated on an enemy Chaos unit or gear; `OGN-225 Solari Chief` kills at any Might but needs the target already stunned, and 423.1.a.2 clears a stun at cleanup step 3d so both halves must be cast the same turn. Blast of Power is the only rung that is both ungated and playable in a Showdown.
SCOPED AGAINST ITS TWIN: `blast-of-power-bloodless-conquer` is the one-card version of this argument and merged seven minutes earlier; it carries the full 466.5 / 466.5.e chain, the zero-excess-damage consequence and the 470 + 485.4 ceiling. What THIS entry adds is a job for OGN-219 Vanguard Sergeant, the pool’s only mono-Order card with no rules text - a refusal of him as “a body that reads no other card” was correctly re-scoped here, because a bloodless conquer reads no text at all.

Steps

Garrison a battlefield of yours and keep Blast of Power in hand; the line is played on YOUR turn, into a battlefield the opponent holds with a small garrison.
Move Vanguard Sergeant (and whatever else) in. 190.3.a.1 applies Contested and 464.2.c.1 makes you the Attacker; 323.9 stages the Combat and 323.13 opens it.
In the Showdown, play Blast of Power (E6 + 1 Order Power) and kill the last defending unit. 806.1.b is the permission; 155 is why Vengeance could not have been held for this window.
The Showdown closes. 465.1's damage tasks require both Attacking and Defending units to remain, and they do not, so no damage is assigned and nothing of yours dies.
466.3.a gives you the combat: you are the only player with units remaining. 466.5 establishes Control and 466.5.d makes it a Conquer.
Any 'when you conquer' text on the bodies standing there fires (383.4.c.2.a puts a unit's Conquer ability on the Chain for the units present when control is gained), and 470 refuses a second Score at that battlefield this turn.

How it ends

engine only — one Conquer with no damage per Blast of Power, hard-capped at two Conquers a turn by 470 with 485.4; three copies a game (103.2.b) and the entry supplies the Conquer rather than the point

Card text verbatim from data/corpus_flat.txt. The content is the ladder's spine: 155 makes a plain spell your-turn-and-Open-State-only, so the CHEAPER and WIDER removal (OGN-229 Vengeance, four words and no gate) is the one that cannot take a battlefield, while the expensive narrow one can. Trap check: the attacker body is in uses[] rather than in a notable, because 466.3.a needs units remaining and the matcher and planner must price it; the excess-damage disjointness is stated so the line is not mistaken for a Tryndamere feeder; 470 with 485.4 is named as the hard cap so three copies are not read as three Conquers; the two banned members of the family are named; the other rungs of the ladder are priced with their gates.
