Soul of Magma

The pinger that asks you to pay twice. A standard pinger taps once per turn for its damage; this one ties its ping to a separate trigger that fires whenever your spell count climbs in the right direction, so the engine is your hand and your tempo rather than your untap step. That swap is the whole design conceit: damage stops being a tempo resource you ration one ping at a time and becomes a yield on the deck you already wanted to build, so a turn that flips two cheap Arcane tricks flips two pings with them. The cost of the model is fragility. The trigger waits on the spell, the spell waits on your hand, and a 2/2 for five sits idle the instant the cards stop coming, so the body never threatens to carry a board the way a recurring tapper does. It also leaves the pilot fully reactive: there is no way to manufacture damage on an empty turn, only to harvest pings off spells already headed for the stack, which makes it a payoff rather than an enabler. Where a self-sufficient pinger grinds down a creature a turn on autopilot, this one rewards a deck dense enough in the relevant spell types that the pings accumulate as a side effect of advancing your real plan.
