Brainstorm the Past

Declare a Creature Type and you may discard
any Creature of that Type to pay {1}. X creatures of that type gain Unearth {3}{r}{g} (Exile permanents from your Graveyard for
their Unearth Cost. Return them to your hand during your opponent's turn and cast them
without paying its mana cost as an instant.)
"How about this, sis? Maybe we could try
looking at the past in this way?" Jira Hammo
