Lore Crafter

When Lore Crafter enters the battlefield create a colorless saga enchantment token with "when this enchantment enters the battlefield, exile target
instant sorcery card with mana value 3 or less
from your graveyard. Do the same for mana
value 2 or less and 1 or less." and "I, II, III—
Copy a card exiled with this enchantment with
mana value less than or equal to the number of
lore counters on it. You may cast the copy
without paying its mana cost."
