Nettle Drone

The pinger that builds itself a combo engine out of the deck around it. A standard Tim taps once and waits; this one untaps every time you cast a colorless spell, and the wave of Eldrazi-adjacent designs gave it a sea of colorless cards to do it with. Devoid is what threads the trigger, since the card needs the spells around it to read as colorless rather than red or blue, and a critical mass of cheap colorless spells turns a one-damage ping into a repeatable burst each turn. Pair it with anything that produces or recurs colorless spells for free, and the untap clause stops being incidental and becomes a loop: cast, untap, ping, cast again. The fragile 3/1 body is a tell that the body is not the point; it is priced to be answered before it goes off. What it represents is a design wager that "colorless spell" could function as a build-around payload the way an artifact count or a spell count does elsewhere, with the untap reframing each colorless cast as a resource the drone converts into reach. Outside a deck stuffed with colorless triggers it is a slow, brittle pinger; inside one it becomes an inevitability engine that ends games a damage at a time.
