Sora, The Slenderman

Changeling (this card is every creature type.)
Haste
When Sora, The Slenderman enters the battlefield, create a token copy of a permanent in
any graveyard, and put it onto the battlefield.
Whenever another non-token creature you control
is destroyed, create a token copy of it and put it
onto the battlefield tapped.
If Sora, The Slenderman would leave the
battlefield, transform it instead.
