Gumno (Mauma) by the Creek

Discard a card: Return Gumno (Mauma) by
the Creek to its owner's hand.
Magecraft — Whenever you cast or copy an
instant or sorcery spell, reveal the top card of
your library. If it's a nonland card, you may cast
it by paying 1 rather than paying its mana cost.
If it's a land card, put it onto the battlefield.
The best adventures are the ones you have with friends.
