Highborn Ghoul

Mono-black aggro has always wanted a clean way through, and intimidate is the keyword that gives it one: a black creature evades everything except artifact creatures and other black creatures, which in most matchups is almost nobody. The body is a deliberate trade. At 2/1 it folds to the slightest blocker, but the design logic is that it will rarely be in combat at all; the single point of toughness is the price paid for an evasive clock that demands an opponent already be in black or holding artifacts to interact in the red zone. That makes it a beater whose value is front-loaded, racing rather than grinding, and it sits in the older lineage of fear creatures (the black-only evasion intimidate later generalized) that asked the same question: can you afford to take two a turn while the black deck assembles its kill? The fragility keeps it honest against the cheapest removal and the occasional black blocker, but the keyword is the whole pitch. This is unglamorous, color-locked evasion at a rate that suits a fast clock over a durable one.
