Aether Chaser
The energy mechanic asked a basic question of every card that produced it: bank the resource or spend it now? This 2/1 first striker answers by making both options live on the same body. It enters with exactly enough energy to buy one Servo, so the payoff is deferred to combat: attack, pay , and mint a 1/1 that stays back this turn but joins the assault on the next. The Servo trigger only allows paying
once per attack, so the card doubles as a slow token engine rather than a burst one. That gives a red shell stacking energy producers a real choice turn to turn: cash the counters in one Servo at a time and grind out a wider board, or hoard them toward a bigger payoff elsewhere and let this swing as a clean two-power first striker. The first strike matters more than the rate suggests: on a one-toughness body it converts a creature that dies to anything into one that wins the early combats it chooses to pick, which keeps the energy faucet attacking and, if you want, producing. The tidy part of the design is that the Servo trigger is optional and gated behind attacking, so the card is never stranded waiting for fuel and never forced to spend energy it would rather save. It is the aggressive end of the energy economy: a cheap clock whose second job is entirely at the pilot's discretion.
