Payoff

Deck

• Legend domains cover Mind and Order — OGN-265 Herald of the Arcane, OGS-021 Lady of Luminosity, SFD-201 Chem-Baroness, UNL-199 Deceiver.

Prerequisites

• THE ARITHMETIC, WITH THE QUANTITIES DECLARED. K = 1 Sentinel, so each hold effect fires 1 + K = 2 times. The Benefactor's trigger: 2 × 2 Gold = 4 Gold per Hold. The Sentinel's own trigger: 2 × 1 rainbow = 2 Power at the start of your next Main Phase. Cost 10 Energy + 1 Power, on two cards.
• THE GOLD IS NEXT-TURN POWER, WHICH ISSUE #48 DID NOT SAY. 315.1 Awaken comes BEFORE 315.2 Beginning Phase, so the Gold created by the Hold (315.2.b.2) enters exhausted and stays exhausted for the whole of that turn — 187.5 makes its ability cost an exhaust and an exhausted gear cannot pay it. In steady state the board does yield 4 Gold-Power plus 2 Sentinel-Power per turn, but the Gold half is offset by one turn and the first Hold pays nothing spendable. world-atlas-sentinel-gold carries the identical correction. Renata Glasc, Industrialist would remove the offset under R25 = A and she is Order, so she is legal here — at the price of a third card and 4 Energy + 1 Power.
• DIFFERENT LINE FROM world-atlas-sentinel-gold, NOT A CHEAPER VERSION OF IT. That entry (2 × SFD-086 + this Sentinel) makes 8 Gold per Hold, but the Atlas is Equipment: it needs TWO more units to hang on and 2 Mind Power of [Equip], so it asks for three units at the battlefield and 3 Power. The Benefactor IS the body: two units, 1 Power, half the Gold.
• IT PRODUCES PER TURN AND LOOPS SPEND PER PASS, so it does not touch the ~9-Energy-per-Power rate of the #21 loop ledger. Against the Seal benchmark (E0 P1, 1 Power to install for 1 Power a turn) it is 1 Power invested for 6 a turn, but only while you hold that battlefield.
• SFD-201 Chem-Baroness is the best legend of the four: 'When you or an ally hold, you may exhaust me to play a Gold gear token exhausted' is itself a hold effect the Sentinel doubles, and 'While your score is within 3 points of the Victory Score, your Gold [Add] an additional 1 Energy'.
• 383.4.d.2.c is a bonus neither card claims: 'If the act of gaining one point from Holding is negated or replaced in any way, the Hold Effect will still trigger.'

Steps

1. Get Eminent Benefactor (6 Energy) and Blue Sentinel (4 Energy + 1 Power) onto the same battlefield and establish Control of it.
2. Survive to your Beginning Phase. In the Scoring Step (315.2.b.2) you Hold it.
3. The Benefactor's hold trigger fires twice (R1 = A): four Gold gear tokens, exhausted.
4. The Sentinel's own hold trigger fires twice: 2 rainbow Power at the start of your next Main Phase.
5. The four Gold ready at your NEXT Awaken (315.1.b). From then on, kill and exhaust each for 1 rainbow Power (187.5) while the previous Hold banks four more.

Per iteration

+4 Gold per Hold (spendable from the following Awaken) and +2 rainbow Power at the start of your next Main Phase

How it ends

engine only — Power and Gold, no points; it converts through Power Nexus (SFD-214) or any Power sink
