Rengar, Pouncing is the only card whose OWN TEXT says so (a second route exists through 355.2.b: OGN-107 Ava Achiever, "When I attack, you may pay 1 Mind to play a card with [Hidden] from your hand, ignoring its cost. If it's a unit, play it HERE" - 359.3.f.2 reads "here" at execution, where she is standing; noted by the #170 walk, 2026-09-07) — and Fresh Beans draws for it

Payoff
Deck
- Any legend with Fury among its two domains (103.1.b.3) — 16 names: Daughter of the Void (OGN-247), Relentless Storm (OGN-249), Loose Cannon (OGN-251), Hand of Noxus (OGN-253), Dark Child - Starter (OGS-017), Mechanized Menace (SFD-181), Purifier (SFD-183), Glorious Executioner (SFD-185), Void Burrower (SFD-187), Virtuoso (UNL-181), Pridestalker (UNL-183), Bloodharbor Ripper (UNL-185), Piltover Enforcer (UNL-187), Rogue Assassin (VEN-139), Butcher of the Sands (VEN-141), Master of Shadows (VEN-143).
- An attack of your own already open, so that there is a Combat Showdown to play him into and a battlefield you are attacking.
Prerequisites
- HE IS THE ONLY REINFORCEMENT THAT CAN REACH THE BATTLEFIELD YOU ARE ATTACKING. 355.2.a limits where a unit may be played to 'the controller's Base or a Battlefield the controller controls', and the battlefield you are attacking is by definition neither — that is the same clause that makes a hidden card useless on the attacking side (811.1.b hides only at a battlefield you control). Sweeping data/corpus_flat.txt for cards that mention playing and attacking returns one unit with the permission: `SFD-025 Rengar, Pouncing`, 'I can be played to a battlefield you're attacking.'
- AND HE ARRIVES IN TIME TO FIGHT. 464.2.c.3.a defers the designation of a body that becomes present after the Attacker/Defender step to 'the Cleanup phase following the action that caused it to become present'; 319.6 makes a Cleanup Outstanding 'After any number of Game Objects enter or leave the Board' and 323.2.a hands out the designation there. So he is an Attacker in the same damage step, and [Assault 2] — 807.1.c, 'functionally short for While I am an attacker, I have +X [M]' — puts him in at 5 Might.
- THE BEANS PAY FOR IT, AND THE REASON THEY WORK OFF-TURN IS THE 381 SPLIT. 381 confines Activated Abilities to 'the Controlling Player's Turn and during an Open State'; Fresh Beans' 'you may exhaust this to draw 1' hangs off 'When you play a unit during a showdown', so it is a Triggered Ability and 383.3.c puts it on the Chain 'during Closed States or Open States on any [player's] turn'. Its cap is its own exhaust — one draw per turn, readied at 415.3.a.
- THE BEANS' POOL IS WIDER THAN THIS PAIR AND WORTH KNOWING. Any unit playable in a showdown fires them: a [Reaction] unit like Rengar, an [Ambush] unit (822.1.b grants the [Reaction] timing), and every hidden unit, because 811.1.b's tail gives a face-down card [Reaction] 'beginning on the next turn'. Rengar is in `uses` because he is the only one that reaches the ATTACKING side; the rest are defensive.
- Priced whole: 2 Energy once for the gear, then 3 Energy + 1 Fury Power per Rengar for a 5-Might attacker that appears after the opponent has committed their blocks, plus a card. Three copies (103.2.b), one draw a turn.
- 144.1.b is not in the way: he is PLAYED, not moved, so the Closed-State prohibition on the Standard Move never applies — and 144.2's exhaust is never paid either, which is the same shape as `SFD-093 Dauntless Vanguard` taking the Attacker designation with no move at all.
Steps
- Play Fresh Beans (2 Energy) at your base.
- On your turn, attack a battlefield: move a unit in, 190.3.a.1 applies Contested and 464.2.c.1 makes you the Attacker. A Combat Showdown opens.
- Inside that Showdown, play Rengar, Pouncing (3 Energy + 1 Fury Power) directly to the battlefield you are attacking.
- Fresh Beans' trigger fires — a unit was played during a showdown. Exhaust it and draw 1 (383.3.c).
- The Cleanup following his arrival designates him an Attacker (464.2.c.3.a, 319.6, 323.2.a); [Assault 2] has him fight at 5 Might (807.1.c).
Per iteration
-1 card, -3 Energy -1 Fury Power, +1 card drawn, +1 attacking body at 5 Might inside an open combat
How it ends
engine — a 5-Might attacker added after blocks are committed, plus one card, for 3 Energy and 1 Fury Power; one draw a turn (415.3.a). Nothing here scores.

AUTHORED 2026-09-07, issue #173. UNL-011 Fresh Beans and SFD-025 Rengar, Pouncing were both in ZERO entries. Card text verbatim from data/corpus_flat.txt; 103.1.b.3, 103.2.b, 144.1.b, 144.2, 190.3.a.1, 319.6, 323.2.a, 355.2.a, 381, 383.3.c, 415.3.a, 464.2.c.1, 464.2.c.3.a, 807.1.c, 811.1.b, 822.1.b opened in the Core Rules file. Both cards legal in both formats; neither is Signature. No unruled reading. The uniqueness claim was swept over the corpus rather than asserted, and it matters because the project's refuse-bucket C ('no [Hidden] card can play the attacker-side role') has exactly this card as its one exception in the whole pool.
