Wish there was room for flavor text: "It is the bump you hear in the night."

Abilities can't trigger from hidden zones, which of hand is one.

I think it would need to be worded more along the lines of

> , Reveal ~ from your hand: ... Activate this ability only if... and more times than..?

Huh. It'd be nice to have 'resolve when revealed' as a trap. Like madness could be.

1) Why can't triggered abilities work from hidden zones though? The draft-matters cards worked from a hidden zone, although those were replacement effects.

2) Feedback I got elsewhere was the same as yours, Vitenka. Make it work like trap cards and let you flash it in cheap. But the flavor of the boogeyman is that it's always lurking, so I don't like that for this particular card.

• triggered abilities use the stack, replacement effects can be applied directly to an event as it happens
• putting the triggered ability on the stack is mandatory - even if "you may" make a decision to not use this one during resolution there needs to be a way to enforce triggered abilities follow the correct timing. The way to enforce this is to only have triggers occur from public zones
• optional replacement effects can remain hidden since there is no need for anything to happen unless the replacement effect is actually invoked
• extra: activated abilities (e. g. the one suggested by Tahazzar) work on a similar basis of "this doesn't go on the stack automatically, only if someone chooses to activate it"

Good point about may abilities going on the stack. I had to explain that to someone at the Battlebond preview, actually
