World Weaver

World Weaver enters the battlefield tapped with
X stun counters on it, where X is equal to twice
the number of creatures in play. Whenever a
creature dies remove a stun counter from World
Weaver. At the beginning of your upkeep if
there are no stun counters on World Weaver, it
has "{t}, Sacrifice World Weaver: search your
library for a Forest card, a Mountain card, a
Plains card, a Swamp card, and an Island card.
Put those cards into play tapped with two stun
counters on them."
