Dayman, the ultimate form

When Dayman, the ultimate form enters the
battlefield, sacrifice Dayman, the ultimate
form if you don't control 3 or more nightcards.
Dayman, the ultimate form gains +2/+2 for
each nightcard on the battlefield.
If Dayman, the ultimate form is put into the
graveyard, deal {x} damage to a target. {x} is the
number of token creatures you control.
These are the lyrics.
