Potapych, God Among Bears

This spell can't be countered.
Indestructible
As long as you control 5 or less bears, Potapych is
not a creature.
When Potapych enters, search your library for a
bear card, reveal it, shuffle and put it on top.
At the beginning of your upkeep, put a +1/+1 counter on each bear you control.
Whenever a creature dealt damage this turn by a bear you control dies, draw a card.
