Lady Octopus, Inspired Inventor

Card advantage usually buys options; here it buys a countdown clock toward free artifacts. The engine keys off drawing your first and second card each turn, so it rewards the incremental draw a control shell already generates rather than a single explosive Windfall, and the counters accumulate whether you want them fast or slow. What makes the tension real is the ceiling: the tap ability only casts an artifact spell with mana value at or below the counter count, so the deck is a ladder. Early on you are freecasting Signets and one-mana artifacts; several turns in you are dropping something with a mana value in the fours and fives for the cost of one tap. That gating turns the card into a deckbuilding puzzle about curve rather than a raw cheat, since it can only fire once per turn and can never exceed what the counters have earned. The 0/2 body is doing exactly what a value engine wants a body to do: survive, block a one-drop, and stay on the battlefield long enough to matter, contributing nothing to the board's offense so the whole card reads as a repeatable free spell attached to a durdle. It is a slow, methodical enabler wearing a villain's frame, closer to a mana rock that pays off draws than to a creature you deploy for pressure.
