Purifing Light of Trast

Destroy all nonland, nonangel permanents.
Then gain 2 life for each permanent destroyed this way.
"And on the final day, his lordship prayed
for fire to burn away the unclean. Trast, our
true lord, gave us the fire we hoped for, even as
it purged our lordship and his flock of unworthy followers..." - Hymn of Trast
