Children's Day

Whenever you cast a Human spell, create a 0/1
white Human creature token named Child with
"When Child enters the battlefield, create a 2/2
white Dog creature token".
—
"Children's day is mother's, father's and teachers'
day, but it is also animal's day.
Whenever you look at a child, there is always
a hidden figure, which is a dog behind,
which is very important."
- Dilma Rousseff, Lost but Seeking.
