-Look at the top five cards of your library. Exile one of them face down and put the rest on the bottom of your library in a random order. You may cast the exiled card without paying its mana cost if it's an instant spell with mana value 2 or less. If you don't, put that card into your hand.
For when the blue player would like one last super desperate "please let there be a Counterspell in my top 5 cards so I don't lose the game" card in their deck. Snark aside, this is close to being "Scry 5, draw a card" with some nonsignificant upside at instant speed for 3 mana.
Is this maybe actually kinda good? Like, if you have enough 1-2 mana instants already in your deck to where you're getting to freecast what you find a reasonable amount of the time, the fact that this card has the fail case of drawing you the best card out of your top 5 might actually make it worth trying out in some decks.
If you don't get the combo piece you want with this card but you do find an instant-speed dig spell, you can dig insanely far with this card (7 cards deep if you chain this into Opt/Consider, 8 cards deep chaining into Brainstorm, 10 cards deep chaining into Peer Through Depths). Now how to fit this in when you already want all the cheap dig spells....
