Nico Robin, Demon Child

When Nico Robin enters, create a Cursed Child token and attach it to Nico Robin.

Mille Fleur — on your upkeep, each opponent creates an
0/1 black and blue Fleur token with, "When this creature enters and on your upkeep, you lose 1 life."
Then if there are ten or more Fleur tokens on the battlefield, destroy all Fleur tokens and up to one target enchantment you control.

"There is no such thing as being born into the world to be alone."
