Duergar Assailant

A combat-restricted Mogg Fanatic that prices itself in either red or white, which is the whole pitch. The classic version pings any target at any time; this one trades that reach for a hybrid pip that lets it fill the one-drop slot in a red deck, a white deck, or any shell running both. The leash to attacking or blocking creatures pays for that flexibility: it cannot snipe a mana dork on turn two or reach an opponent's face, and it sits inert until combat is declared. The compensation is a chump-trade that gets to pick its victim. The trick is the timing, not the math. Because a sacrificed creature deals no combat damage, the floating point from the ability is all you get, so the play is to let blocks lock in, then sacrifice it to push a trade that combat alone would not have closed: a 1/1 attacker is going to die to a 2/2 blocker, but the extra point can finish an already-wounded blocker the moment it commits. The design lives entirely in the asymmetry of the combat step, where one point of damage decides whether a creature lives or dies. It is a small, honest piece of a low-curve aggressive deck, the kind of body that wants the board to clog up just long enough to cash itself in for something larger.
