[Equip] 1 Calm Power (1 Calm Power: Attach this to a unit you control.)
If this was attached to me this turn, I have an additional +2 Might.
Payoff
Deck
- Legend domains are Calm and Body: SFD-193 Grandmaster at Arms IS the legend, and the Brutalizer is Calm.
Prerequisites
- THE CARD IS WRITTEN AS A ONE-SHOT AND THE LEGEND MAKES IT A SUBSCRIPTION. 'If this was attached to me this turn' is a condition on the turn, not on the unit; in a normal deck you pay 1 Calm Power once and the +2 lapses at the next turn. Reattaching it - to the same unit or another - satisfies the condition again, and the legend's attached-to-attached ability costs no Energy at all.
- IT WORKS ON THE SAME UNIT. 434.1.f - 'Attaching a card to a new Top-Most Card will cause it to Detach from the card to which it is currently Attached' - describes the move; nothing requires the destination to be different, and the effect only asks whether the attachment happened this turn.
- ONE RENEWAL A TURN. The legend's cost is an exhaust, so 315.1.b readies it once and there is no second activation this turn regardless of Energy.
- THE +2 IS ON TOP OF THE +1 MIGHT BONUS the Equipment already gives (434.1.d), so a unit carrying it is +3 on the turns the legend re-arms it and +1 otherwise.
- Its cousin jax-grandmaster-warmogs-buff runs on the same free ability with the opposite payload: that one moves a buff onto a NEW body permanently, this one refreshes a temporary bonus on the body you want big today. They stack in one deck and share only the legend.

Equip Brutalizer to a unit (1 Calm Power): +1 Might from the Might Bonus, plus +2 because it was attached this turn
Steps
- Equip Brutalizer to a unit (1 Calm Power): +1 Might from the Might Bonus, plus +2 because it was attached this turn.
- Next turn the +2 has lapsed and the unit is +1.
- Exhaust the legend - the attached-to-attached ability, no Energy - and reattach the Brutalizer to the unit you want big, which may be the same one.
- The condition 'if this was attached to me this turn' is satisfied again: +2 back on top of the +1.
- Repeat every turn.
Per iteration
+2 Might renewed every turn for one exhaust of the legend and zero Energy
How it ends
engine only - one renewal a turn, and the bonus lapses if you skip it

How this entry was audited
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 2026-09-06 (docs/phase0/walks/2026-09-06-issue62-section3.md), issue #62 section 3. SFD-042 Brutalizer appeared in no entry before this. The video's own title calls it the 'infinite weapon hack' and the entry deliberately does not: the legend's cost carries an exhaust, so it is once a turn, which is an ENGINE and not an INFINITE by this catalogue's definition. Card text verbatim from data/corpus_flat.txt. Trap check: no attack designation; no [Repeat]; no [Temporary]; no token; no recall; 434.1.f is what makes a same-unit reattachment legal to describe. Depends on no unruled reading.
