Patron of the Secrets

Rogue or Shapeshifter offering (You may cast this
card any time you could cast an instant by sacrificing
a Rogue or Shapeshifter and paying the difference in
mana costs between this and the sacrificed Rogue or
Shapeshifter. Mana cost includes color.)
At the beginning of your end step, create a token
that's a copy of Patron of the Secrets except the
token isn't legendary, then draw a card for each
creature named Patron of the Secrets you control.
