Flying {3}{W}, Exile Heron-Blessed Geist from your graveyard: Create two 1/1 white Spirit creature tokens with flying. Activate only if you control an enchantment and only as a sorcery.
"When once winter has ahold,
Not willingly does she withdraw
Her icy touch, wistfully caressing—
The deepened air sleeps its cold."
—Aline Corralurn, "Late Thaw"
