Generator Servant

A ritual that walks onto the battlefield and waits. Most acceleration in red burns up the moment you cast it: a spell that adds mana and heads to the graveyard, value spent in a single window. This one banks itself as a 2/1 body until you want the mana, then sacrifices for two colorless and, crucially, staples haste onto whatever creature spell that mana helps cast. That haste clause is what justifies the whole design. Plain ramp into a fatty leaves the fatty sitting there for a turn, exposed to sorcery-speed removal and contributing nothing; here the payoff swings the same turn it lands. The body is the cost-control: a 2/1 that can chump or trade keeps the card from being a dead draw when you have no haymaker to ramp into, and the tap-and-sacrifice means the acceleration is a one-shot you choose the timing on rather than an enters-the-battlefield burst you spend immediately. It rewards a curve built around a single big creature drop, the kind of deck that wants to turn a four-mana payoff into a turn-three attacker, and it asks nothing in return except that you commit the body when you pull the trigger.
