Assaultron Dominator

Energy has always been a self-contained resource: the you bank is spent inside its own closed loop, useful only to cards printed to notice it. What this design does is fold energy into the combat step of an artifact-creature deck, so that the two energy it hands you on arrival become a per-attack toolbox rather than a one-time payout. Each combat, any artifact creature you control that swings can spend an to pick up a +1/+1, first strike, or trample counter, and the choice is made attack by attack: pump the blocker-facing threat with first strike this turn, break through a wall with trample the next. Because the counters are permanent once placed, the energy is not spent so much as converted, each point becoming a sliver of durable board presence rather than a temporary buff that evaporates at end of turn. That is the quiet weight of the design: it turns a resource historically defined by its transience into a slow accumulation engine, provided you keep the energy taps flowing and the artifact creatures attacking. The body itself is small and does the work of a payoff, not a threat, which is the honest read of what it wants around it: a wide artifact-creature board and other sources of to feed the counter it dispenses one attack at a time.
