Creepy Crawler

Similarly, each time a Horror creature, Nightmare creature, enchantment creature, or face-down creature you control attacks an opponent, that opponent become afraid of you for the rest of the turn, regardless of what happens to the creature that attacked. Attacking a planeswalker or battle, however, won’t cause anyone (your opponent or the planeswalker) to become afraid of you; most planeswalkers have seen some wild stuff.

You don’t need to control Creepy Crawler to make an opponent afraid of you. (Mechanically, I mean. Please don’t jump scare your opponents!)

Playtest cards aren’t legal for play in any tournament format other than Mystery Booster Limited formats. On the other hand, we expect they will spice up a wide variety of non-tournament games (as long as everyone’s on the same page about using them!).
