Thor, God of Thunder

Flying, vigilance, indestructible
If Thor, God of Thunder would be put into your graveyard from the battlefield, exile it instead, and put three time counters on it. At the beginning of your upkeep, remove a time counter. When there are no time counters left, you get an emblem with "Creatures you control get +2/+2."
If your devotion to green and white is less than seven, Thor isn't a creature.
