Halo Scarab

A body that dies once and keeps paying out. Most two-drops that leave graveyard value spend a card getting there; this one folds its entire afterlife into a single line that turns a spent creature into a Treasure whenever you have two mana and want a color you don't have. The 2/1 is deliberately cheap and disposable, because the card wants to trade in combat, chump a bigger threat, or feed a sacrifice outlet, and then hand you fixing from the yard at a moment of your choosing. That double role is the point: an Artifact Creature reads as an artifact the entire time it lives, so it triggers artifact-matters payoffs and dies to artifact removal before it ever becomes a Treasure, then converts into more artifact once the token exists. And because the card exiles itself the instant the Treasure is made, the payout is one-shot per copy rather than a recurring ramp loop, which is what stops it from spiraling into an engine. What it really offers is a smoothing effect stretched across two turns and two zones, letting an early beater double as insurance against a color screw several turns later. The reason it fits aristocrats shells, tempo boards, and greedy multicolor manabases alike is that it never asks to be the plan; it asks only to be spent twice.
