Aether Swooper

Energy was a closed loop: a resource you could only generate from cards that printed it and only spend on cards that asked for it, which meant every energy producer carried a quiet obligation to also be an energy payoff worth the entry. This Vedalken splits that obligation across two clean halves. The enter trigger banks two energy on arrival, enough to seed the engine the moment the body hits the table; the attack trigger then turns that stored charge into Servo tokens, one per swing, so long as the counters hold out. The arithmetic is deliberately tight: two energy in, two energy out, a self-funding token machine that runs exactly one cycle on its own before it needs an external supply to keep spinning. That is the whole tension of the energy mechanic compressed into a single two-mana evasive creature. A flyer that pays for its first Servo and then asks the deck to fuel the rest, it works as both a battery and a drain depending on what surrounds it, which is the design problem energy always posed: a card that makes the resource is worth little if nothing spends it, and a card that spends it starves without a maker. Putting both functions on one cheap body was the cleanest answer to that problem the mechanic produced.
