Emperor's Vanguard

Haste, first strike
Whenever Emperor's Vanguard deals combat
damage to a player, 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.)
"Emperor Lucin asks to make sure the road ahead is
safe to travel on."
