Seasons Past (SOI)

Sorcery

Return any number of cards with different mana values from your graveyard to your hand. Put Seasons Past on the bottom of its owner's library.

The seeds of new life take root in the soil of old.

The phrase “different converted mana costs” compares the mana costs of cards in your graveyard to one another, not to Seasons Past. You may return a card with a converted mana cost of 6.

If a card in your graveyard has {X} in its mana cost, X is considered to be 0.
