Kaneki, Reaper of Men

When Kaneki, Reaper of Men enters the battlefield, create three Kagune tokens and attach
them to Kaneki, Reaper of Men.
Whenever Kaneki, Reaper of Men deals damage
to a human, it gets +1/+1.
When Kaneki, Reaper of Men dies, it transforms.
After all I've been through, you think something like
that would hurt?
