The Last Unicorn

Forest Walk, Haste
If the Last Unicorn would be put into the graveyard from play, put a 1/2 White Creature token with protection from red called Lady Amalthia into play under your control.
Lady Amalthia has: during your upkeep put a time counter on Lady Amalthia. When there are six of these counters, remove Lady Amalthia from the
game and return the Last Unicorn to your hand.
Last Unicorn's life is equal to the number of forests you control
