For Challenge # 031. This was the reminder text for "Goal" that I removed because it took up too much space. Common Goals would have it, but not this uncommon goal which has enough extra words to make the text too small:

(You may cast this face down and declare it a goal for . If you are attacked by four or more creatures in the same turn, you may turn ~ face up.)

Oh, as an alternative idea which I think is cool, but adds more rules: Instead of casting this card for face down...:

(Cast this spell face down and declare it a goal. You may pay any amount of mana, and for each you spent on casting ~, put a mystery counter on ~. If you are attacked by four or more creatures in the same turn, you may turn ~ face up, but only if it has three or more mystery counters on it).

In other words, now we can make goals of any generic casting cost, and can also hide the goals cost. Even, occasionally, bluffing with a goal.

Ah, trap cards. Yes, I considered introducing this kind of thing as my new card type.
