Renasar, Almighty

When Renasar enters the battlefield creatures you control get +1/+1 for each pair of Forest and
Plains you control and gain trample until end of
turn.
At the beginning of your upkeep flip a coin, if you
win the flip, creatures you control get +1/+1 for
each pair of Forest and Plains you control and
gain trample until end of turn.
O mighty one, we tremble before thy strength.
