Gixian Infiltrator

The trigger fires on the sacrifice, not the death, which puts this in a different lineage from the classic aristocrats that drain or ping when a creature dies. Because it reads the act of sacrificing rather than the thing sacrificed, it counts every token, every artifact, every land you feed to an outlet, and it does not care whether the permanent had value on its own. That widens the fuel base considerably: a payoff keyed to creature deaths ignores your Treasures and Clue tokens, but this one banks a +1/+1 counter for each of them. The counters also change the shape of the reward. Where a card like Blood Artist turns a sweeper into a burst of drain triggers, this one is on the wrong side of that math: a board wipe destroys the two-drop and takes its accumulated counters with it, so the growth you have banked evaporates rather than cashing out. It is a threat that wants to close a game before the board resets, not survive one. The other catch is dependence: it does nothing without an outlet, and nothing at instant speed on its own turn unless the machinery is already in play; the body arrives, then waits for the deck to start spinning around it. Read as a design, it is a compact statement of what a sacrifice deck asks from a threat: cheap, permanent-agnostic, and rewarded for the transactions the deck was making anyway.
