This also feels uncommon, I don't think the Sudden Impact type effect has been lower than that.

Your right, this card was more of what I'd like to see from cards with the minor "peek" theme we have going.

The peek theme might be cool, provided that we reward that. Is there a way to make that matter? Most obvious way is to use "Name a card" effects, but anything else, especially to reward playing multiple cards with that effect?

There are also traps which provide a large bonus to knowing about them in advance.

That's the reason I made this card. Although the "peek" is helpful against traps, we should have the cards that let you peek interact with the hand, like this card which deals damage based on hands in hand, or I have a green creature that gets bigger if the oppenet you peek at has 3 or more instant or sorceries. White one could gain you life, blue or black could mill if the opponent has so many of a card type ect.
