Glassblower's Puzzleknot

A battery you cash in twice. Most of the energy producers from this era handed you counters and walked off the table; this one lingers as a sacrifice outlet, so the four total energy it generates arrives across two windows you choose rather than one. The scry rides along on both, which is the quieter half of the design: an energy deck wants to dig toward its payoffs, and a card that smooths two draws while stockpiling fuel does double duty without asking for a slot it wouldn't already earn. The sacrifice clause is where the discipline lives. Holding the artifact lets you bank the second activation for a turn when you actually need the energy spike or the dig, rather than dumping everything on cast, and the cost gates it behind a blue commitment so the smoothing isn't free. It's a deliberately humble piece of the energy chassis: not a payoff, not a threat, just a slow-release reservoir that splits one card between an enter trigger and a later activated ability. The whole Puzzleknot cycle worked this way, dividing a one-shot effect across the moment it lands and the moment you break it; this one leans hardest into resource-banking, the concern that mattered most to decks trying to hoard energy for a later swing.
