To go other routes for draw, I would consider including Grothama, All-Devouring to attack/fight/"sac" a bunch of "excess" creatures for draw, or Skullmulcher does similar in a pure sac way, or perhaps Ohran Frostfang, Regal Force, Toski, Bearer of Secrets, Benefactor's Draught, Mind's Eye, War Room, and while Nissa, Voice of Zendikar is off the Elf theme, it's still effective for more than draw
Its pretty easy to end up in a position where you attack with three tokens, draw two or three Hare Apparent, then drop those into play
This typically happens when extra ink is added to the printing plates or rollers, leaving a card with splotches of ink that make it look like it was stained
The attack trigger could kill someone before blockers are ever declared (which means thats the right direction to send the Commissar)
