The Earth Cycle

Seasonal
When The Earth Cycle enters the battlefield, put
a +1/+1 counter on each land you control. They
become 0/0 Elemental creatures that are all
colors in addition to their other colors and types.
As long as it's spring, land creatures you control
have indestructible. As long as it's summer, they
get +1/+0 and have first strike. As long as it's
autumn, they get +0/+1 and have reach. As long
as it's winter, they can't be blocked.
