Electrostatic Infantry

The prowess payoff that keeps its winnings. Prowess itself only buffs the turn you cast a spell, giving back the size at cleanup; this Dwarf trades that instant-speed spike for a permanent one, banking a +1/+1 counter on every instant or sorcery you cast and stacking them across turns rather than spending them in a single combat step. That shift changes what kind of deck wants it: prowess creatures reward a burst of cheap spells all at once, but a counter-based grower rewards a steady drip of them, so a hand full of cantrips and one-mana burn compounds into a threat that outgrows removal windows instead of shrinking back to a 1/2. Trample is the detail that makes the accumulation matter, because a spells deck rarely fields the board presence to force damage through blockers, and a growing body that ignores chump blockers turns those banked counters into a real clock. The trigger counts the cast, not the resolution, so a countered or fizzled spell still feeds the engine, and it fires on both halves of your spell-heavy turn regardless of whether anything sticks. It is a small body asking for a very specific shell, and in that shell it does the one thing prowess never could: it keeps growing after the turn ends.
