Infinite Power

Deck

Legend domains cover Mind and Order.

Prerequisites

Main Deck empty.
Infinite Energy already established (this loop spends 9 Energy per Power).
TOURNAMENT RULES 505 IS WHY THIS LOOP MAY BE SHORTCUT AT AN EVENT, AND IT WAS CITED BY NOTHING (upgrade 2026-09-12, #191 batch 27; Tournament Rules, labelled). **505.2** - *"Players performing a loop must have each iteration of the loop be identical with no conditional actions"* - and **505.9** - *"If a sequence of actions is non-deterministic, it may not be shortcut and iterations must be performed manually."* Read against Core Rules 416.5, two or more cards recycled to the Main Deck simultaneously go to the bottom in RANDOM order, so a loop that recycles 2+ per pass is non-deterministic unless it draws all of them back. **The condition is checkable and this entry meets it**: the Main Deck is empty by construction, so every card recycled in a pass is drawn back inside that same pass and the random order never selects a subset. That means the *"zero spare draws"* invariant this catalogue maintains for a different reason - a fifth draw is Burn Out (431.1.a) on one side and a stranded random card on the other - is load-bearing a SECOND time, against a procedural rule it was not written for: it is exactly what makes the loop shortcuttable rather than hand-iterated at a table.
THE EMPTY MAIN DECK IS A ONE-TURN STATE THAT DESTROYS ITSELF, WHICH NO ENTRY SAYS AND NONE CITED. This loop’s premise is an empty Main Deck, and the Core Rules put a clock on it that is separate from 431.1.a’s Burn Out on a fifth draw. 315.4.b is the Draw Phase task, "The Turn Player draws 1", and 315.4.b.1 is automatic: "If there are no cards remaining in their Main Deck to draw, the Turn Player has been Burned Out." There is no "may". The Burn Out then costs three things in sequence — 431.2.b, "Recycles their trash into their Main Deck", whose own reminder reads "When multiple cards are Recycled to the Main Deck at the same time, those cards must be randomized", which ERASES the known bottom this loop stands on; 431.2.c, "Chooses an opponent to gain 1 point"; and 431.2.d, "Completes the remainder of the action that caused them to burn out", restated at 315.4.b.2 as "After completing the Burn Out the Turn Player still Draws 1." Riot’s worked example at 431.2.d IS this situation, word for word: "A player attempts to draw 1 during their Draw Phase while their Main Deck is empty." Since 315.4 Draw Phase precedes 316 Main Phase, THE DECK MUST BE EMPTIED AND THE LOOP MUST WIN INSIDE THE SAME MAIN PHASE — an empty Main Deck cannot be carried across a turn boundary at all, and the landing is exact rather than approximate: the turn before the kill must end with enough cards for that turn’s forced removals and no more. A mandatory mill makes it tighter, because 431.1 is written over moving cards "to any other zone in excess of the number of cards remaining", so 431.1.b Burns you Out for a [Burn N] exactly as 431.1.a does for a draw. And the one escape does not exist: VEN-022 Endless Riches is the pool’s ONLY card printing "Skip" (one row in the corpus), it is Fury, it banishes your hand and trash on entry, and its own "[Burn 7]" is itself a Burn Out under 431.1 against an empty deck — so it cannot save a loop even in principle.
THE GEAR THIS LOOP RUNS ON IS *NOT* AN EQUIPMENT, SO ITS ANSWER SET IS NARROWER THAN THE REST OF THE CLASS — AND NO ANSWER REACHES IT AT `[Reaction]` SPEED (added 2026-09-13, #200). A loop is a SERIAL dependency, so every link is load-bearing and one removal ends it. Of the fifteen enemy-facing printings that reach a gear, **exactly one is `[Reaction]` — `SFD-011 Angle Shot` — and it is a DETACH that names *"an Equipment"*.** `OGN-212 Forge of the Future` and `SFD-117 Ancient Henge` carry `type: gear` and an EMPTY tag list, so neither is an Equipment and neither is ever attached: **a gear that is never attached cannot be detached, so Angle Shot cannot touch them at all.** Of the remaining fourteen, four carry `[Action]` and reach a Showdown on either player’s turn (806.1.c.1) and the rest are plain spells that 155 confines to their controller’s own Main Phase. **SO EVERY ANSWER TO THIS LOOP MUST BE CAST ON THE OPPONENT’S OWN TURN, A FULL TURN AHEAD AND TELEGRAPHED** — the loop itself runs entirely inside your Main Phase. That is the second disjointness on the same halving of the gear pool this project already records from the exhaust side, where the 40 Equipment carry ZERO exhaust symbols and 40 of the other 67 do. **AND THE FORGE IS ALREADY DYING EVERY PASS, WHICH CUTS BOTH WAYS**: its own text is *"Kill this: Recycle up to 4 cards from trashes"*, so the recycle is PAID by killing it and the line rebuys it each pass — but an opponent’s kill removes it WITHOUT handing over the recycle, and that recycle is this loop’s only refill against a ledger that runs with zero spare draws. Whether the Burn Out lands in the same pass depends on where in the pass the kill falls, which only this entry’s own ledger can settle and none of these entries states.

Steps

Recycle a rune to float 1 Power of its domain (legal at any priority, rule 429.3 / 164.2.b).
Kill Forge of the Future to recycle Forge and Retreat. Deck: 2 cards.
Play Lecturing Yordle (3 Energy): draw 1.
Play Retreat (1 Energy) on Lecturing Yordle: it returns to hand and you channel the recycled rune back exhausted.
Replay Lecturing Yordle (3 Energy): draw the remaining card. Replay Forge (2 Energy). Repeat.
Weave any other trash card into Forge's recycle to rebuild a perfect hand.

Per iteration

-9 Energy, +1 floating Power of any rune domain you control. Unbounded given infinite Energy.
