Basilisk Jungle

Basilisk Jungle enters the battlefield tapped.
At the beginning of your end step, if you
control four or more Forests and Basilisk
Jungle isn't a creature, you may put three
+1/+1 counters on it. If you do it becomes
a 0/0 green Dragon creature with defender
and flying. It's still a land.
Copses, reasonably safe. Thickets, probably fine. Groves, begin to worry me. Don't go near a wood!
