Ghirapur Aether Grid
A repeatable pinger that costs no mana to fire, only the tap of two artifacts you already control, and that single design choice is what separates it from the Prodigal Sorcerer lineage it descends from. Where a Tim-style creature dings once per turn and dies to any removal, this hides the damage engine inside an enchantment and spreads the activation cost across your board. Two untapped artifacts buys one damage; in a deck flooded with cheap artifacts, that arithmetic scales into a machine gun that can clear a board of small creatures or close a game out across several turns. The cost structure is the tension worth noting: every activation taxes your artifacts, so the same Servos, Thopters, and mana rocks you might want attacking or producing mana are instead being tapped for pings, and you only get as many shots as you have pairs to spare. It also dodges summoning sickness entirely, since artifacts you control can be tapped the moment the Grid resolves, and it answers planeswalkers and players as readily as creatures. The card is a payoff that demands a critical mass of permanents to justify itself, rewarding wide artifact-token strategies that already want to flood the board, and turning that width into reach an artifact deck otherwise lacks.
