Llanowar Spell Savant

Flash
When Llanowar Spell Savant enters the battlefield, choose one—
• Counter target noncreature spell unless its controller pays {1}.
• It explores. (Reveal the top card of your library.
Put that card into your hand if it's a land. Otherwise,
put a +1/+1 counter on this creature, then put the
card back or put it into your graveyard.)
