Days of Youth

All your creatures explore in the order of your
choice (Reveal the top card of your library. Put that
card into your hand if it's a land. Otherwise, put a
+1/+1 counter on this creature, then put the card back
on top or into your graveyard.).
Memory --- At the beginning of your upkeep, if
your library has 30 cards in or less, if Days of
Youth is in your graveyard, you lose 1 life.
