Shadow Alley Denizen

Evasion engines usually live on the attacker, baked into a single creature's keyword or a one-shot pump spell. This one externalizes it: the 1/1 body is disposable, but every black creature that follows it onto the battlefield hands evasion to whichever creature needs it that turn, including the denizen itself. Intimidate is the operative verb because it keys off color rather than flying or menace, so a board built around mono-black bodies turns the granted creature into something nearly unblockable: opponents need an artifact creature or a black blocker to interpose, and most boards have neither on demand. The design only pays off in density. One denizen on a thin curve does nothing worth noticing; a wide, black-heavy aggro shell turns each new entry into an attack-routing trigger that pushes damage past a clogged board or shoves the last points through a stalled race. It rewards committing fully to black, a color already among Magic's most heavily rewarded for monocolor discipline, since splashes dilute the very thing intimidate reads. The targeting is generous (any creature, including an opponent's, though you will rarely want that), so the evasion can be banked on a single threat or sprayed across a developing board as bodies arrive. A modest enabler whose ceiling rises and falls with how hard the deck around it commits to black creatures.
