Sophie, Sanguine Suitor

When Sophie enters, create two Blood tokens. Sophie's power equals number of Blood tokens you control.

Whenever Sophie deals damage to a creature, if the creature survives, create a number of Blood tokens equal to the damage dealt. If the creature dies, you create one tapped Treasure token instead.

Whenever Sophie deals combat damage to a player, you
may sacrifice any number of tokens. She deals damage equal to the number sacrificed to another target player.
