Thrull Wizard

A creature that exists to police its own color. The activated ability counters only black spells, which makes this a deeply parochial piece of design: a hatebear pointed squarely at the mirror, a body whose interaction is meaningless against any deck that is not also playing black. That narrowness is the whole idea. Fallen Empires was built around competing factions, and a black-on-black counter ability speaks to that internal-strife flavor more than it ever functioned as a Constructed tool. The mechanics reinforce how cheap the answer is meant to be: the counter is a soft tax, repeatable at low cost, and the controller can wriggle out by paying a small fee, so it pressures tempo rather than denies a spell outright. The 1/1 frame tells you the rest. This was never going to attack into anything; it sits back, holds up mana, and threatens to make an opponent's black removal or threat awkward to resolve. The repeatable nature is the genuinely interesting wrinkle, since a soft counter you can fire every turn warps how the opponent sequences their black spells far more than a one-shot would. But the color restriction caps the ceiling so hard that the card now reads as a curiosity of a set that designed around factional conflict rather than around cross-archetype playability.
