Shmooze, Panda Soul Mage?

Shadow, hexproof
Whenever you cast a spell, create a black 2/3
panda token with "Sacrifice this creature: target
player loses 2 life and add one mana of any color
to your mana pool." This ability only triggers
once each turn.
Whenever another creature dies, target player
loses 1 life and you gain 1 life.
