Pharymel, High Luminae

Whenever you cast your first instant or sorcery
spell each turn, target player puts the top three
cards of their library into their graveyard.
Whenever an instant or sorcery spell with
converted mana cost one or less is put into a
graveyard this way, you may cast that card until
end of turn any time you could cast an instant.
The Church of the Luminae delights in the Ascension,
for they prize what they don't understand above that
which they do.
