Tin Pi, the Veteran Caregiver

Defender, Trample, Indestructible
Tin Pi cannot have -1/-1 counters placed on him.
Whenever a beast or bird you control dies, put a
+1/+1 counter on Tin Pi and he loses defender.
Birds you control gain Sing Tin Pi a Song:
{t}: Add {u} or {g} to your mana pool.
Beasts you control gain Caregivers Compassion:
gaining vigilance and {g}: regenerate this beast.
{2}{u}: If you control a wizard flip Tin Pi.
"The beasts and birds suffer the most from the
carelessness of war..."
