Tranquil Path {1}{U}
Enchantment
Whenever a creature you control attacks and isn't blocked, it explores. (Reveal the top card of your library. Put it into your hand if it's a land. Otherwise, put a +1/+1 counter on that creature, then you may mill that card.)
“We could just planeswalk right to where we're going, but where's the fun in that?”
