Repel the Abominable

A fog with a tribal clause, and the tribe is the joke that lands. On a plane overrun by Lovecraftian horrors and Eldrazi-twisted abominations, a damage-prevention spell that cares specifically about Human versus non-Human sources turns the flavor into a mechanical lever: your Human creatures can still swing and connect while every monster on the far side of the table whiffs entirely. Standard fog effects are symmetrical pauses; this one is deliberately lopsided when your board is Human and theirs is not, which is the real design move. It blanks a battlefield of zombies, spirits, eldrazi, dragons, and demons while a Human aggro deck alpha strikes behind the wall. That asymmetry comes with a catch: against a creature base that happens to be Human, or against burn and noncombat damage routed through Human-typed sources, it does far less than a plain Fog would. When the tribal split does not break your way, the prevention shell simply never opens all the way, which is what you trade for the one-sidedness. As a piece of color-pie work it sits squarely in white's history of asymmetric protection, the same instinct behind Worship and Solitary Confinement, but pointed at a creature type rather than a damage source or a permanent count.
