Ravenous Squirrel

Aristocrats decks have always asked one card to do too much: grow with each sacrifice, refill the hand the engine empties, and cost little enough to run beside the rest of the machine. Most designs deliver one of those; this hybrid one-drop folds all three into a single 1/1. The passive counter cares specifically about the act of sacrificing, not death: feeding a sacrifice outlet is what grows the body, so combat losses and removal do nothing here even as they do for a drain payoff like Blood Artist or Zulaport Cutthroat. That distinction matters, because it ties the Squirrel's clock directly to how hard you are running the outlet. The activated ability does the grindy work: three mana to gain a life and draw, offsetting the resources a sacrifice deck bleeds through, and because the artifact or creature you feed it also trips the passive trigger, each activation grows the Squirrel too. The price is what keeps that draw from spinning free; it asks real mana per loop rather than becoming a self-contained engine. The drain effects it plays beside aim outward at the opponent's life total; this one turns inward, converting fodder into board presence and cards, rebuilding the very resources a long sacrifice game tends to lose on. The result is a threat, a card-advantage outlet, and a sacrifice sink stacked into one body, at a mana value low enough that slotting it in never costs tempo.
