Payoff

Deck

• Legend domains are Calm and Body: the source plays UNL-191 Wuju Master, whose '[Level 11] Your units enter ready' is why Anivia can attack the turn she lands. CORRECTED 2026-10-14 (#361): Level 11 is why she can attack the turn she LANDS, not why she can attack sooner; on basic runes the first equipped attack is T5 either way - see the notable 'SHE ENTERS EXHAUSTED UNLESS THE LEGEND IS LEVELLED'.

Run play

• The second burn buys Anivia's life, not a kill, and Level 11 only hides her for a turn

Prerequisites

• SIX IS THE NUMBER THE SOURCE GIVES AND IT IS THE NUMBER THE CARDS GIVE. Two instances of 'deal 3 to all enemy units here' is 6 to everything at that battlefield. 383.4.e.2.a says an attack trigger's condition is checked once per combat, so each of the two instances fires exactly once - there is no third. CORRECTED 2026-10-14 (#361, from the run play docs/plays/2026-10-14-the-second-burn-buys-anivias-life-and-level-11-only-hides-her.md): six is right, and what the second three are worth is not counted in kills. In the play the sweep met a seven-body garrison (four 3s, two 4s and a 5). The first sweep killed the four 3s, and her 9 (Level 6) would have killed the three survivors, which had 3 marked each, with 1 + 2 + 1 = 4 of it: the second sweep killed nothing the first sweep and her 9 did not. What it bought is the damage step. 465.1: 'If both Attacking and Defending units remain at this battlefield, the following Tasks become Outstanding, in the specified order:' - with no defender left nobody assigns her damage, so she lived and conquered (466.5.d). With one sweep every defender of 4 or more Might survives with 3 marked and still assigns its full Might (465.2.c), so she dies whenever those defenders total at least her Might (142.4.b): 9 at Level 6, 8 below it. With two sweeps that bar moves to defenders of 7 or more.
• IT NEEDS A REAL GARRISON TO FIRE AT ALL. 'When I attack' requires the Attacker designation (383.4.e, 464.2.c.3), which only exists inside a Combat, which only stages when units of opposing players are present (323.9). Walking Anivia into an empty enemy battlefield conquers it and deals nothing.
• SHE ENTERS EXHAUSTED UNLESS THE LEGEND IS LEVELLED. 143.4 is the default; the source's answer is UNL-191's [Level 11] 'Your units enter ready', which the same deck's XP engine pays for - gromp-arena-svellsongur-xp is that engine. CORRECTED 2026-10-14 (#361, from the run play docs/plays/2026-10-14-the-second-burn-buys-anivias-life-and-level-11-only-hides-her.md): this reads Level 11 as what makes the attack possible, and it does not make it earlier. Landed on T4 without it (E7 + 2 Body, all seven runes on the board), she is readied by your Awaken - 315.1.b, '1. The Turn Player readies all Game Objects they control that are able to be readied.' - and is equipped and attacks on T5, the same turn as the Level 11 line (the cost notable shows T4 is one Energy short for both). What Level 11 buys is that she is never on the board during their turn: no window for OGN-229 Vengeance (Order, E4 + 2, 'Kill a unit.'), and no warning before they place their T4 plays. It needed four Hunt bodies holding A by the T5 Hold in the play (12 XP). The cheapest break needs no card: a 4-Might body kept in their base on their T2 walks into A on their T3, while Level 6 is not live, and kills two of the Hunt bodies (465.2.c.3); the T5 Hold then reaches 8 XP, and the Level 11 attack slips to T6.
• 11 Energy and 4 Power all in (Anivia 7 + 2 Body, Svellsongur 3 + 1 Calm, plus its [Equip] of 1 Energy + 1 Calm), so this is a late-game card, not a curve play. CORRECTED 2026-10-14 (#361, from the run play docs/plays/2026-10-14-the-second-burn-buys-anivias-life-and-level-11-only-hides-her.md): this notable said '9 Energy and 2 Power', and its own addends make 11 Energy and 4 Power, two Body and two Calm. A rune pays Power by being recycled (164.2.b, 'Recycle this: [Reaction] — Add [C].'), which takes it off the board until it is channelled again, and the turn player channels two runes a turn (315.3.b). Going first on basic runes you have 2, 4, 6, 8 and 10 runes on T1 to T5, less every rune recycled before. Svellsongur's earliest turn is T2 (E3, its Calm from a recycled rune), which leaves 7 runes on T4, and Anivia plus the Equip is 8 Energy: T5 is the first turn on which she can be equipped and attack. Cards that add Energy (UNL-093 Dragonsoul Sage) were not walked.
• The Might Bonus is +0, so the Svellsongur adds no body - all it does is duplicate the text.
• WHAT ANSWERS IT - ADDED 2026-10-14 (#361, from the run play docs/plays/2026-10-14-the-second-burn-buys-anivias-life-and-level-11-only-hides-her.md). OGN-213 Hidden Blade (Order, E2 + 1: 'Kill a unit at a battlefield. Its controller draws 2.') is hidden at the battlefield she attacks for one rune of any domain (811.1.b), and from the next turn it may be played any time a [Reaction] card may (811.6) - including while her two attack triggers are on the chain, a Closed State where only [Reaction] plays (309.1, 309.1.a). She dies before either sweep resolves. 'Here' is read on execution (359.3.f.2), and a unit no longer on the board has no location (the example under 359.3.e.12), so neither sweep lands and the garrison stands. The play marks that join as a reading, since the 359.3.e.12 example is written for spells; under the other reading the sweeps still kill the garrison, and she is dead either way. One card and one rune, against Anivia, the Equip and the turn. Of the Body/Order cards that kill a unit the caster chooses at any Might (Hidden Blade, Vengeance, SFD-164 Drag Under, OGS-012 Blast of Power), none prints [Reaction] and only Hidden Blade gains it, so it is the only one that kills her before a sweep resolves. The second sweep alone has a cheaper target: Svellsongur sits in your base from the turn it is played, and OGN-224 Salvage (Order, E2 + 1: '[Action] (Play on your turn or in showdowns.) You may kill up to one gear. Draw 1.') removes it on their turn; with one sweep the play's garrison trades her off and leaves B uncontrolled (466.5.b).

Steps

1. Equip Svellsongur to Anivia, Primal (1 Energy + 1 Calm Power).
2. Move her into an enemy battlefield that has a garrison. The Combat stages (323.9) and opens (323.13).
3. 464.2.c.3 designates her the Attacker; 383.4.e puts BOTH instances of 'When I attack' on the chain.
4. Each deals 3 to all enemy units there: 6 total, before the damage step.
5. Whatever survives fights her 8 Might.

Per iteration

6 damage to every enemy unit at the battlefield per attack, instead of 3

How it ends

engine only - one doubled sweep per attack, bounded by how often she can attack
