Payoff
Deck
- Legend domains are Fury and Body: UNL-183 Pridestalker (Rengar), which the source plays; Star Spring is Colorless.
Prerequisites
- THE DRAGGED UNIT MAKES ITS OWN CONTROLLER THE ATTACKER, ON YOUR TURN. 190.3.a and 190.3.a.1 apply Contested according to the moved unit's CONTROLLER, not according to who caused the move, so an enemy body you pull onto your battlefield contests it for them and 464.2.c.1 makes them the Attacker. 464.2.e.1 then puts the Defender's triggers on the Combat Chain last, which by 340.1 resolves them first. That is the whole point of the card and it is #58's finding applied to a different pair.
- 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.
- 'The first time a player plays a non-token unit here each turn' IS THE THROTTLE. Once a turn, and the unit played must be a real card - 185 makes a token ineligible, so a token generator cannot substitute for Inferna.
- THE RETURN IS A MOVE, NOT A RECALL. Star Spring says 'move another unit they control here to its base', so 446.1 applies and any 'when I move' text on the returning unit still fires; 456 never comes into it.
- Different pair from faefolk-challenger-forced-attacker, which uses the same UNL-112 with UNL-105 to buy one forced attack. This one buys a forced attack EVERY turn, because Star Spring pays the Faefolk's way home for free.
Steps
- Star Spring is your battlefield and you control it. The Faefolk is in your base, ready.
- Standard Move the Faefolk to Star Spring (144.4.a, cost is the exhaust). Its trigger: move an enemy unit to that battlefield.
- That enemy unit applies Contested for ITS controller (190.3.a.1), so the Combat that stages makes them the Attacker on your turn (464.2.c.1).
- Play Inferna at Star Spring with [Ambush] (2 Energy): it is the first non-token unit played there this turn, so Star Spring lets you move another unit you control there back to its base - the Faefolk.
- Next turn the Faefolk is ready again (315.1.b) and the whole thing repeats.
Per iteration
one enemy unit dragged onto your battlefield per turn, for 2 Energy and the Faefolk's exhaust; the Faefolk goes home free
How it ends
engine only - one forced reposition a turn, throttled by Star Spring's once-per-turn clause

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-table-of-fourteen.md), issue #62 section 2.6. The catalogue already had UNL-112 in faefolk-challenger-forced-attacker; what is new here is that Star Spring turns a one-shot into a per-turn engine by paying the return trip. The rule that makes the drag worth anything - Contested keys on the moved unit's controller, so THEY become the Attacker on YOUR turn - was established by the #58 walk and is applied, not re-derived. Card text verbatim from data/corpus_flat.txt. Trap check: no [Repeat]; no [Temporary]; no token is played at the Spring (185 would make it ineligible anyway); the return is a move and not a recall; 143.4 means Inferna arrives exhausted, which does not matter since it is played for the trigger. Depends on no unruled reading.
