Welcome to the Rabbit Hole

When Welcome to the Rabbit Hole is reveled
from the top of your library, you may have target creature that explored this turn gain first strike, haste, hexproof, lifelink, menace, and vigilance until end of turn.
Target creature you control 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 that creature, then put the card back or put it into your graveyard.)
