Undermined Galaxy

Search your library for a card, put that card into
your hand, then shuffle.
You may cast a spell with mana value equal to or
less than the number of italicized abilities you
have triggered this turn from your hand without
paying its mana cost.
(Italicized abilities are abilities found on cards
such as Delirium, Revolt, Landfall, Magecraft,
Goyfcast, Morbid, Spell mastery, Heroic, etc... )
