Alvina, Hunt Mother

Flash
Each Instant and Sorcery in your graveyard has Flashback. It's Flashback cost is equal to it's
mana cost plus {2}.
Whenever you could Scry, you may instead look
at that many cards form the top of your library
and cast an Instant or Sorcery from among them
with mana value {4} or less without paying. Put
the rest into your graveyard.
