Seabird's Folly

On each player's upkeep, Flip a Coin:
If the coin comes up heads, gain 1 life and
draw a card.
If the coin comes up tails, lose 1 life, discard
a card, and create a 1/1 Bird Spirit with Flying
and "This creature cannot be blocked by
non-spirit creatures"
"Bad luck to kill a seabird!"
