Contemplate

Imagine, imagine, imagine.
(Name a number and reveal the top two cards of your
library. You may put a revealed card, that has the
same mana value as the named number, into your
hand. Put the rest on the bottom of your library in
any order. If you didn't put a card into your hand,
create a fractal enchantment token.)
Reveal the bottom card of your library. If it is an instant, put it into your hand.
