Runo Stromkirk // Krothuss, Lord of the Deep

Oracle text

Flying When Runo enters, put up to one target creature card from your graveyard on top of your library. At the beginning of your upkeep, look at the top card of your library. You may reveal that card. If a creature card with mana value 6 or greater is revealed this way, transform Runo. // Flying Whenever Krothuss attacks, create a tapped and attacking token that's a copy of another target attacking creature. If that creature is a Kraken, Leviathan, Octopus, or Serpent, create two of those tokens instead.
