Leeroy, Soul of the Ocean

At the beginning of your upkeep, scry 1.
Whenever you cast an instant or sorcery spell, draw card. Then, discard a card.
{4}{u}{u},{t}: Put a token onto the battlefield that is
a copy of target creature your control.
What would an ocean be without a monster lurking in the dark? It would be like sleep without dreams.
- Werner Herzog
