Purify the Mind

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.)
Deal 3 damage to target creature or planeswalker.
If you own 3 or more fractals, deal 5 damage
instead.
