Into the Frozen North

Target creature you control explores. If that
creature is a Viking, it gains first strike until
end of turn. (Reveal the top card of your library.
Put that card into your hand if its a land. Otherwise,
put a +1/+1 counter on the creature, then put the
card back or put it into your graveyard.)
Out here, knowing the terrain is crucial. We need
every advantage we can get.
