Defense of the Wilds

At the beginning of your upkeep, if an opponent controls three or more creatures, sacrifice
Defense of the Wilds, search your library for up
to two Beast creature cards, put those cards onto
the battlefield, then shuffle.
"As the last line of defense for the Ardenglen Wilds,
Lyrial's every step weaves a symphony with the forest,
her purpose as clear as the rustling leaves, to safeguard nature's sanctuary."
