The Ostrich's Bouquet

Whenever a nontoken creature enters or leaves
your graveyard, create a white 0/1 Ostrich Griffin
token with haste and the following ability:
"Ostrich Griffin tokens gets +1/+0 for each other
Ostrich Griffin you control. Exile it at the
beginning of the next end step."
Toby didn't get off the damn boat, so a hoard of
ostriches came.
