Best Menace cards in MTG

Menace: A creature with Menace can only be blocked by two or more creatures.

Menace is a strong evasion ability that forces opponents to commit multiple blockers, making it great in aggressive decks and for pushing through combat tricks or Deathtouch. It punishes opponents with few creatures and pairs well with pump effects since they often cannot afford to double-block. Combine it with Trample to make multi-blocking even less appealing.
