[Accelerate] (You may pay 1 Energy + 1 Fury Power as an additional cost to have me enter ready.) When I conquer, draw 1.

When you hold here, activate the conquer effects of units here.
Payoff
Deck
- Legend domains need Fury; the source builds it under a Kai'Sa legend and the Arena is Colorless, so 103.1.b.1 never touches it.
Prerequisites
- THE ARENA IS WHAT MAKES A CONQUER TRIGGER REPEAT, and that is the whole entry. A Conquer happens once per battlefield you take (469.1); a Hold happens every turn you keep it (469.2, 315.2.b.2). 'Activate the conquer effects of units here' is the bridge.
- THE BATTLEFIELD IS RANDOM AND CANNOT BE DOUBLED UP: random 1 of 3 in Duel (485.5) and Skirmish (487.5), chosen in Match (486.5); 103.4.c and Tournament Rules 402.1 forbid a second copy by name.
- [Accelerate] IS WHY SHE CAN CONQUER THE TURN SHE LANDS. 143.4 makes units enter exhausted; 805 lets the additional cost of 1 Energy + 1 Fury override it. Without it the first draw waits a turn.
- IT IS ONE CARD A TURN, WHICH IS THE HONEST FIGURE. The Arena activates conquer effects once per Hold, and 'When I conquer, draw 1' is one draw. The source's 'you get to draw every single turn that you hold' is exactly right and nothing multiplies it.
- Cheapest Arena payload in the catalogue: 4 Energy and no Power against ivern-arena-sentinel-hold's board or kennen-stargazer-arena-flow's three cards.
Steps
- Take Reckoner's Arena with Kai'Sa, Survivor, paying [Accelerate] (1 Energy + 1 Fury) so she enters ready and can conquer the same turn. 'When I conquer, draw 1' pays once.
- Survive the opponent's turn.
- Your Beginning Phase Holds the Arena (315.2.b.2): 1 point.
- The Arena activates the conquer effects of units there - Kai'Sa's draw fires again.
- Repeat every turn she holds.
Per iteration
+1 card and +1 point per turn from one battlefield, for a 4 Energy body
How it ends
engine only - a card a turn while she holds

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. OGN-039 Kai'Sa, Survivor appeared in no entry before this. It is the plainest use of Reckoner's Arena in the catalogue and it is worth having precisely because the other three Arena entries all pay for something else on top - this one measures what the battlefield is worth on its own. Card text verbatim from data/corpus_flat.txt. Trap check: no attack designation is needed, since a Conquer comes from Establishing Control (466.5.d) or a Showdown (348.2.a.1); no [Repeat]; no [Temporary]; no token; no recall. Depends on no unruled reading.
