Rikku, Resourceful Guardian

Counters usually accumulate in one direction: you add them, they stay, the board slowly tilts. This design turns the counter itself into a portable resource, something you pry loose from an opponent's threat and bolt onto your own. The Steal ability reads like theft because it is: a +1/+1 counter, a keyword counter, any marker sitting on a creature an opponent controls can migrate across the table one at a time, weakening their board while building yours. The sorcery-speed restriction is what keeps the larceny fair: you cannot ambush a blocker mid-combat by ripping the pump off it, and you cannot flash the engine online in response to their play. It works on your terms, during your main phase, as a patient grind rather than a trick.

The evasion clause closes the loop and hands the whole thing a clock. Any time you put a counter on a creature, whether by casting a spell, activating Steal, or triggering some outside proliferate effect, that creature slips past their blockers for the turn. So the engine is not just resource conversion; it is a way to turn every counter placement into an attack step. A deck that treats counters as its currency gets a payoff that grows its threats and makes them unblockable in the same motion, and the artificer body at the center of it is cheap enough to be an early anchor rather than a top-end reward.
